Understanding Newton's Laws of Motion

Front

Which of the following best describes Newton's First Law of Motion? An object will remain at rest or in uniform motion unless acted upon by an external force.

Back

An object will remain at rest or in uniform motion unless acted upon by an external force.

Front

A book is lying on a table. According to Newton's First Law, what will happen to the book if no external force is applied?

Back

It will remain at rest.

If a car is moving at a constant velocity, which of the following statements is true according to Newton's First Law? The car is accelerating. The net force acting on the car is zero. The car is decelerating. The car is experiencing a net force in the direction of motion.

Back

The net force acting on the car is zero.

If the mass of an object is doubled while the force applied to it remains constant, what happens to the acceleration of the object according to Newton's Second Law?

Back

It halves.
