Force and Motion Review

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 static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from moving when a force is applied.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in motion of an object.

Front

What is net force?

Back

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

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied, expressed as F=ma (Force = mass x acceleration).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the Law of Inertia?

Back

The Law of Inertia is another name for Newton's First Law, stating that objects will not change their state of motion unless acted upon by an external force.

Front

What is kinetic friction?

Back

Kinetic friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What is rolling friction?

Back

Rolling friction is the force that resists the motion of a rolling object on a surface.
