Newton's First Law

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What happens to a moving object when balanced forces act on it?

Back

It continues to move at a constant speed and in the same direction.

Front

What is a net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in a net force of zero.

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, resulting in a net force that causes a change in motion.

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will resist changes in its motion more.

Front

What is an example of inertia in everyday life?

Back

A passenger lurching forward in a car when it suddenly stops.

Front

What is the relationship between force and motion?

Back

A force is required to change the motion of an object; without force, an object will maintain its current state of motion.

What is the formula for calculating net force?

Back

Net Force = Force applied in one direction - Force applied in the opposite direction.
