Speed and Accelerations

When an object’s distance from another object is changing,

• it is in motion.
• it is speeding. 
• it is accelerating.
• it is moving at a high velocity.

Speed equals distance divided by

• time
• velocity
• size
• motion

A train that travels 100 kilometers in 4 hours is traveling at what average speed?

• 50 km/h
• 100 km/h
• 2 km/h
• 25 km/h

total distance traveled divided by total time taken to travel that distance

• velocity

• motion

• acceleration

• average speed

The formula for calculating speed is...(x means multiply; / means divide)

• time x distance

• distance x speed

• distance / time

• time / distance

A dog runs on the sidewalk 3 km/h.

• Speed

• Acceleration

• Velocity

Describe the speed of the object from 4-6 seconds using the distance vs. time graph.

• Increasing speed
• Decreasing speed
• Not moving
• Constant speed

Describe the speed of the object from
2-5 seconds using the speed vs. time graph.

• Increasing speed
• Not moving
• Decreasing speed
• Constant speed

How far will a person go if they jog for 2 hours at a speed of 12 km/hr?

• 6 km
• 0.5 km
• 10 km
• 24 km

What is the formula to calculate speed?

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