Forces and Newton's Laws of Motion

Front

What is force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What is Newton's First Law of Motion?

Back

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

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. It can be 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 inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

What is sliding friction?

Back

Sliding friction is the force that opposes the motion of an object sliding over a surface.

Front

What is rolling friction?

Back

Rolling friction is the force that opposes the motion of an object that is rolling over a surface.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms.
