BI 13- Force/Motion (Dec 1)

Front

What is force?

Back

A push or pull that can change the motion of an object.

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, causing a change in motion.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is gravity?

Back

A pulling force that attracts objects toward each other.

Front

How does mass affect motion?

Back

The greater the mass of an object, the greater the force needed to move it.

Front

What is friction?

Back

A force that opposes motion between two surfaces in contact.

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.

Front

What is velocity?

Back

The speed of an object in a specific direction.

Front

What is momentum?

Back
