A skate boarder falls from a height of 5m. It took him 1s to hit the ground. What was his speed when he hit the ground? Assume that acceleration during his fall due to gravity is 10m/s²

• 10m/s

• 5m/s

• 15m/s

• 2m/s

Yu De stepped on the gas pedal. His golf cart went from 7m/s to 25m/s in 3 seconds. What is the acceleration of the golf cart?

• 6m/s²

• 7m/s²

• 8m/s²

• 9m/s²

Total distance an object travels with direction.

• km

What is the correct unit for velocity in kinematics?

• m/min

• mi/hr

• d/t

• m/s

What is the correct unit for acceleration in kinematics?

• m/s

• m/min²

• m/s/t

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

A change in velocity over time is known as:

• acceleration
• constant speed
• average speed
• displacement

Velocity is both ____ and _____. 

• speed , direction 
• direction, mass
• volume, density 
• direction, magnitude
