What happens to the normal force when a person lifts one foot while standing?

Back

The normal force does not change.

Front

If a force of 8 Newtons is applied to a crate moving at a constant velocity, what can be said about the frictional force?

Back

The frictional force is also 8 N.

Front

Can motion occur without a net force acting on an object?

Back

Yes, motion can occur when there is no net force.

Front

How does friction affect the motion of an object?

Back

Friction opposes the motion of an object and can affect its velocity.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on an object at rest, while kinetic friction acts on an object in motion.

Front

What is the formula for calculating acceleration?

Back

Acceleration = Net Force / Mass.

What is the significance of Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net force.
