Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

The change in position of an object over time.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal and can cause an object to accelerate or change its motion.

Front

What happens when a balanced force is applied to an object?

Back

The object's speed and direction remain constant.

Front

What happens when an unbalanced force is applied to an object at rest?

Back

The object will move in the direction of the force.

Front

What is friction?

Back

A force that opposes the motion of an object, often caused by contact with another surface.

Front

How does mass affect motion?

Back

The greater the mass of an object, the more force is needed to change its motion.

Front

What is acceleration?

Back

The rate at which an object's velocity changes over time.

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 an unbalanced force.
