Front

How do you calculate speed?

Back

Speed = Distance ÷ Time.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no movement.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal, causing an object to move or change direction.

Front

If a runner completes a 5-mile race in 40 minutes, what is their average speed?

Back

Front

What is the formula for distance?

Back

Distance = Speed × Time.

Front

If a cyclist rides at a speed of 15 miles/hour for 3 hours, how far do they travel?

Back

45 miles.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).
