Question

Which statement best summarizes the central idea of “Applications of Newton’s Laws”?

Newton’s laws can explain the forces that occur between objects every day.
Newton’s laws are useful for explaining why we should make good decisions.
People should use caution when moving objects, due to objects’ inertia.
Newton’s laws are outdated and cannot be used for present-day problems and situations.

Answer 1

The answer is: Newton’s laws can explain the forces that occur between objects every day.

Gravity as a force which causes any two bodies to be attracted to each other.

The gravitational effect increases as the size of an object increases. Earth s surrounded by its own gravitational field.

The weight of an object is the amount of force acting on the object due to gravity. SI unit for weight is newton (N).

Answer 2

Newton's three forces, normal, tension and friction, are present in a surprising number of physical situations

Newton's Laws, that describe the relationship between an obejct and the forces acting upon it, apply in almost every physical situation, from quantum mechanics to electricity.

The correct answer is:

Newton’s laws can explain the forces that occur between objects every day
