Forces and Motion Chapter Review

Front

What is Friction?

Back

Friction is the force that opposes the motion of two objects sliding against each other.

Front

When objects collide, what happens?

Back

A force is exerted on each object.

Front

What type of force is the moon orbiting the Earth at a constant speed?

Back

Balanced Force.

Front

How is a force described?

Back

A force is described as a push or a pull.

Front

In a collision, do both objects experience the same amount of force?

Back

Yes, both balls experience the same amount of force but in opposite directions.

Front

What is a Balanced Force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an Unbalanced Force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

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 unless acted upon by a net external force.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).

Front

What is Gravity?

Back

Gravity is the force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.
