Force and Motion Review HS

Front

What is the net force acting on an object?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction.

Front

What is a force?

Back

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

Front

What are the units of force?

Back

Force is measured in Newtons (N).

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 at a constant velocity unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is periodic motion?

Back

Periodic motion is motion that repeats at regular intervals, such as swinging or rocking.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between surfaces.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the Earth and an object.
