Answer to Question #288745 in Atomic and Nuclear Physics for Looya

Question

Question 17

One of the main reasons why people constantly try to reduce the mass of objects is to be able to increase its speed and acceleration. All of the factors have an effect on each other. If something has much more mass, then exerting more force will make it move faster. This is an application on which law of motion? Explain

Answer 1

This is an application of Newton's second law, which states that acceleration is directly proportional to force and inversely proportional to mass:

$$a=\dfrac Fm.$$
