Exam Review: Forces

Front

What is Newton's First Law of Motion?

Back

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

Front

Define inertia.

Back

The resistance of an object to any change in its state of motion.

Front

How does Newton's Second Law of Motion relate to acceleration?

Back

The car's acceleration is directly proportional to the net force applied and inversely proportional to its mass.

Front

What effect does mass have on inertia?

Back

The greater the mass, the greater the inertia.

Front

Provide an example of Newton's Third Law of Motion.

Back

A rocket launching into space.

Front

What is the formula for Newton's Second Law of Motion?

Back

F = ma (Force equals mass times acceleration).

Front

Explain the concept of net force.

Back

Net force is the total force acting on an object after all the forces are combined.

Front

What is the relationship between mass and acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases if the net force remains constant.

Front

What is the significance of friction in motion?

Back

Friction opposes the motion of objects and can cause them to slow down or stop.

Front

How does gravity affect motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion and acceleration.
