Motion Unit

What is the formula to calculate speed?

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

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

Alan travels 100 km in 5hrs. Find his average speed in km/h

• 5km/hr
• 10km/hr
• 50km/hr
• 20km/hr

What does this graph represent?

• Constant Speed
• Acceleration
• Not moving

On a distance vs. time graph, the steeper the slope _____

• the slower the speed
• the faster the speed
• less acceleration
• greater 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

Constant speed is:

• When the speed increases or decreases
• When the speed of the object does not change

Calculate the speed:
A Car traveled 240 Km in 5 Hours

• 48 Km/Hr
• 1200 Km/Hr
• 4.8 Km/Hr
• 0.02 Km/Hr

Which cyclist is travelling faster at t = 3s? (You need to know that both cyclists are traveling at constant speed, meaning that both x(t) lines are straight)

• A

• B
