Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling us down.

Front

What does it mean to accelerate?

Back

To accelerate means to increase the speed of an object.

Front

What is a graph of motion?

Back

A graph of motion shows how an object's position changes over time.

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What is the formula for speed?

Back

Speed = Distance ÷ Time.

Front

What happens when two forces are balanced?

Back

When two forces are balanced, they cancel each other out, and the object remains at rest or continues moving at a constant speed.

Front

What happens when two forces are unbalanced?

Back

When two forces are unbalanced, they cause the object to accelerate in the direction of the greater force.
