Forces

Front

What is force?

Back

A force is a push or pull acting upon an object as a result of its interaction with another object.

Front

What is Newton's 1st Law of Motion?

Back

An object in motion tends to stay in motion and an object at rest tends to stay at rest until acted on by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is dependent upon the net force acting upon the object and the mass of the object (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

How do you calculate force?

Back

Force can be calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What happens to acceleration if mass increases while force remains constant?

Back

If mass increases while force remains constant, acceleration decreases.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

Mass and acceleration are inversely related when force is constant; as mass increases, acceleration decreases.

Front

What is an unbalanced force?

Back

An unbalanced force is a net force that causes an object to accelerate.
