How can you find distance if you know speed and time?

• Add speed and time

• Divide speed by time

• Multiply speed by time

• Subtract time from speed

What is instantaneous speed?

• The average speed over a journey

• The speed at a specific moment in time

• The total distance traveled

• The time taken to travel a distance

How is average speed different from instantaneous speed?

• Average speed is always higher

• Average speed does not involve distance

• Average speed is calculated over a longer period of time

• Average speed is the speed at a specific moment

When does speed become velocity?

• When a direction is added

• When time is added

• When force is added

• When distance is added

Which of the following is an example of velocity?

• 10 meters per second

• 10 seconds

• 10 meters per second north

• 10 meters

What is the main difference between speed and velocity?

• Velocity includes direction

• Speed is always higher

• Speed includes direction

• Velocity is always higher

Can the same mathematical principles be used for both speed and velocity?

• No, only for average speed

• Yes, but only for instantaneous speed

• No, they are completely different

• Yes, they are similar except for the directional component
