Speed, Velocity, Acceleration

Front

Speed = _______________

Back

Distance / time

Front

Which statement best describes the cart?

Back

The cart moved at a constant velocity of 0.5 m/s for the entire 7 seconds

Front

Which of the following is a unit of speed?

Back

km/hr

Front

At what speed would a car have to move in order to travel 20 kilometers in 2 hours?

Back

10 km/hr

Front

This occurs when an object speeds up, slows down, or changes direction.

Back

Acceleration

Front

Define speed.

Back

Speed is the distance traveled per unit of time.

Front

What is the difference between speed and velocity?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final velocity - Initial velocity) / Time taken

Front

If a car is moving at a constant speed of 60 km/hr, what is its acceleration?

Back

0 m/s² (since there is no change in speed).
