• Inertia

• Direction

• Speed

• Motion

Descriptions of motion such as up/down, left/right, north/south, east/west

• velocity

• motion

• direction

• gravity

The measure of the rate of an object in the amount of time AND direction

• motion

• inertia

• direction

• velocity

The measure of how hard it is to slow down or stop an object

• momentum

• inertia

• gravity

• motion

The force of attraction between two objects due to their mass. This force pulls you towards the center of the Earth.

Matt had a toy truck weighing 15 grams and a toy car weighing 6 grams. Using the same amount of force on each toy, he pushed them both across the desk. The car reached the other side of the desk in 1.5 seconds, but it took the truck 3.5 seconds to reach the other side of the desk. Why did the car travel the same distance in a shorter amount of time?

• The truck had more mass and traveled at a faster speed than the car.

• The car had more mass and traveled at a faster speed than the truck.

• The car had less mass and traveled at a faster speed than the truck.

Some clocks keep time by using a weight to move the clock hand around the clock face. The weight is attached by a rope. The weight moves down a small amount as each minute passes. What force moves the weight down so the clock hand shows the right time?

• magnetism

• gravity

• friction

• buoyancy
