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 are unbalanced forces?

Back

Forces that cause a change in the motion of an object, resulting in a net force that is not zero.

Front

What is inertia?

Back

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

Front

How does friction affect motion?

Back

Friction is a force that opposes the direction of motion, acting in the opposite direction.

Front

What happens to a resting object due to inertia?

Back

It will remain at rest unless acted upon by an unbalanced force.

Front

What is the net force when all forces acting on an object are balanced?

Back

The net force is 0N.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is a net force?

Back

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

Front

What is the effect of an unbalanced force on a moving object?

Back

It will cause the object to accelerate, decelerate, or change direction.

Front

What is static friction?

Back

The frictional force that prevents two surfaces from sliding past each other when at rest.
