How is speed different from velocity?

• Speed includes direction, while velocity does not

• Velocity includes direction, while speed does not

• Speed and velocity are the same thing

What is the formula to calculate speed?

• Speed = time × distance

• Speed = distance ÷ time

• Speed = time ÷ distance

If a car travels 100 miles in 2 hours, what is its speed?

• 50 mph

• 150 mph

• 200 mph

How do you calculate average speed?

• Average speed = total distance ÷ total time

• Average speed = total time ÷ total distance

What is the difference between average speed and instantaneous speed?

• Average speed is the speed at one moment, while instantaneous speed is the speed over a period of time

• Average speed is the speed over a period of time, while instantaneous speed is the speed at one moment

• Average speed and instantaneous speed are the same thing

Describe what acceleration means in terms of motion.

• The speed at which an object moves

• The change in speed or direction over time

• The distance an object travels

How can you tell if an object is accelerating?

• If it is moving at a constant speed

• If its speed or direction is changing

• If it is at rest

What does it mean if an object has a constant velocity?

• The object is not moving

• The object's speed and direction are not changing

• The object's speed is changing but its direction is not
