The offence is defined as an unlawful, criminal act, which is dangerous and which causes the death of the victim. The straight line relationship is expressed in Hooke’s law. The elastic limit is the maximum force that can be applied to a wire/spring such that the wire/spring returns to its original length when the load is removed. Thus, Newton’s first law can be demonstrated. ). Newton’s first law can also be applied in places such as: Newton’s second law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. Created: Apr 21, 2020. This is a very useful way of changing the base (in this formula, the base does matter! This is the elastic limit of the spring. Gross Negligence Manslaughter - This is a common law offence, which can be committed via an act or an omission. A football lying on a field will remain idle until someone kicks it. As the magnitude of weight is increased, the spring stretches more and becomes longer. £17.99 New AS and A-Level Sociology: AQA Complete Revision & Practice (with … Unlawful Act Manslaughter is a common law offence and isn’t defined under any particular statute. The law means that in every interaction, there is a pair of forces acting on the two interacting objects. The aim of this experiment is to find the effect of adding masses on the extension of the spring. In this region, the extension of the spring is directly proportional to the load. This apparatus is set up. For example, in the case of R v Kennedy, the defendant supplied the victim with heroin. Newton’s first law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. Natural Moral Law - Revision Notes (A LEVEL AQA RS 2017 NEW SPEC) (no rating) 0 customer reviews. In fact, at the trial, expert witnesses argued that a competent anaesthetist would have realised the signs of the oxygen tube disconnection after about 15 seconds, rather than the four minutes that the defendant took, and even then only after being alerted by the alarm on the machine. Newton’s second law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. Newton’s laws of motion are three physical laws that describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. A good quote to use in your exam answers comes from Lord Mackay LC, in Adomako: “whether having regard to the risk of death involved, the conduct of the defendant was so bad in all the circumstances as to amount in their judgment to a criminal act or omission”. Hence, its unit is (N/m). Gross Negligence Manslaughter - This is a common law offence, which can be committed via an act or an omission. This point is shown in Figure 2 as Fracture. However, it was more recently defined very clearly in the case of R v Adomako. In a vertical launch of a rocket (Figure 3), the weight of the rocket and drag (air resistance) act downwards. In equation form, Newton’s second law can be expressed as. Although a spring is described in this case, Hooke’s law holds good to any object, provided the proportionality limit has not been exceeded. Where serious harm is recognised, students should consider that a Murder charge may be more appropriate, as there is the possibility that the defendant might satisfy the requirement for “malice aforethought implied”, as illustrated in the case of R v Vickers. 10 g mass is added to the holder and the extension is recorded. MRN: OCR B (MEI) A Level Mathematics Year 1/AS (Pure) Answers and full worked solutions to the Test yourself questions, and full worked solutions to all Target your revision questions, Exam-style questions and Review questions can be found here. At the time, the throwing of the box off the pier was considered a civil offence, rather than a criminal one, so the defendant could not be found guilty of unlawful act manslaughter. Newton’s laws of motion are three physical laws that describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. MRN AQA A-level Law. Physics A-Level Resources for AQA, OCR and Edexcel. The act must be unlawful in a criminal sense. Preview. This follows Hooke’s law, which states that the extension of an elastic object (like a spring) is directly proportional to the force added. In fact, it was argued that the reasonable man, in other words, other competent anaesthetists, would have noticed the disconnected tube much earlier than the defendant and so harm would not have resulted. In this article, Hooke’s law, a demonstration to understand the law, elastic limit and applications of Hooke’s law are discussed. A constant of proportionality (k) is inserted in the equation to remove the constant of proportionality. Exam Practice answers. Once the load is increased above a certain limit, the spring fails to return to its original shape and size even after the load is removed. Cases involving drug taking are interesting to note. The oxygen tube became disconnected and consequently the victim died. My Revision Notes: AQA A-level Law. Recognition of serious harm is not required for danger to be established. … This is an act which is unlawful and would be considered dangerous. According the the judgement in R v Lawrence and reaffirmed in R v Adomako, the risk to the victim must be of death, rather than simply a risk of some injury. The property that allows any material to regain its shape is called elasticity. Mathematics. NB: In the above example, I have not written what base each of the logarithms is to. A civil wrong is not enough, as illustrated in the case of R v Franklin, where the defendant threw a box off a pier, killing a swimmer. In general, the first law defines the force qualitatively, the second law offers a quantitative measure of the force, and the third asserts that a single isolated force doesn’t exist. Another good quote to use is from Lord Hewart CJ, in R v Bateman, where the court argued that “to support an indictment for manslaughter theprosecution must satisfy the jury that the negligence of the accused… showed such disregard for the life and safety of others as to amount to a crime against the State and conduct deserving punishment.”. The spring constant is different for different materials: the larger the value of k, the stiffer the material. Now Test Yourself Answers. AS Papers 1 & 2 In R v Adomako, the defendant was an anaesthetist, whose job it was to monitor amongst other things, the oxygen supply to the patient during a routine eye operation. The spring constant is the force per unit extension. This is because there was no apprehension of violence, which is a necessary part of a criminal assault charge. The thrust from the propulsion of the rocket acts upwards. This constant of proportionality is known as spring constant (or force constant). In the case of R v Lamb, the defendant pointed and fired a revolver, killing the victim. This covers all the topics and modules for all specifications including 2410, 7401, 7402. In general, the first law defines the force qualitatively, the second law offers a quantitative measure of the force, and the third asserts that a single isolated force doesn’t exist. When pulling the wagon with some amount of force (F), it accelerates and starts to move. Beyond the plastic region, some brittle materials (e.g. The section from origin to the point P is a straight line. When pulling these two wagons with the same amount of force, acceleration in the second wagon (a2) will be less than that of the first wagon (a1). The point P is referred to as the proportionality limit. For small loads, the spring returns to its original shape once the load is removed. AQA A-Level Biology Revision For each of the papers below, there are revision notes, summary sheets, questions from past exam papers separated by topic and other worksheets. However, it was more recently defined very clearly in the case of R v Adomako. It summarises what you need to know on Natural Moral Law for the new 2017 AQA Religious Studies specification. Some materials have very low elastic limit and they do not obey Hooke’s law at all.
