Kinematics Review

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 the formula to calculate speed?

• S = t/d
• S = d/t
• S = d x t
• S = t x d

What is velocity?

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

Which is correct?

• speed = distance x time
• speed = speed divided time
• speed = Distance divide time
• Speed = time x speed

What is happening at D?

• Stationary
• Accelerating
• Fast steady speed; moving away from the starting position
• Slower steady speed; moving away from the starting position

What is happening at E?

• Stationary
• Accelerating
• Fast steady speed; moving away from the starting position
• Steady speed; returning to start position

Velocity is both ____ and _____. 

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

Which of the following is a unit for acceleration?

• km/s
• m/s²
• mi/hr
• ft
