_______________ is how fast an object changes over time. 

• speed
• velocity
• momentum
• acceleration

When you tell the direction and speed of an object, you give its

• motion
• velocity
• acceleration
• mass

What does this graph represent?

• Constant speed
• Acceleration
• Not moving

A baseball is thrown a distance of 50 meters. What is the speed if it takes 2 seconds to cover that distance?

• 100 m/s

• 25 m/s

• 52 m/s²

• 100 seconds

Speed is equal to 

• Distance/Time
• Time/Distance
• Time x Distance
• Acceleration

Speed is different from velocity because

• Velocity has a direction
• Speed uses Distance /Time
• Velocity doesn't include time
• Velocity doesn't include distance

During which interval is the object speeding up?

• A to B
• B to C
• D to E
• E to F

What is motion?

• It's like the ocean

• Any change in an animal or person's position.

• Motion is like acting

• Any change in an object or person's position over time.
