Front

What is motion?

Back

A change in an object's position.

Front

What is acceleration?

Back

When a moving object speeds up, slows down, or changes direction.

Front

How can you describe an object's motion?

Back

With measures of distance, direction, and time.

Front

What is gravity?

Back

A force that pulls objects toward each other, like a force that pulls a car down a hill.

Front

How does surface area affect falling speed?

Back

A smaller, more compact object like a crumbled piece of paper will fall more quickly than a flat piece of paper.

Front

What is force?

Back

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

Front

What is velocity?

Back

The speed of an object in a specific direction.

Front

What is friction?

Back

A force that opposes motion between two surfaces in contact.

Front

What is the relationship between mass and gravity?

Back

The more mass an object has, the stronger the gravitational pull it exerts.

Front

What is a balanced force?

Back

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