Speed, Velocity and Acceleration Retake practice

Front

What is speed?

Back

Speed is a measurement of how fast an object is moving, defined as the distance traveled per unit of time.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity over time.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / 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

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

Back

Average speed = Total distance / Total time = 100 miles / 2 hours = 50 mph.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction.

Front

What is a scalar?

Back

A scalar is a quantity that has only magnitude and no direction.

Front

If a person is standing still, what is their speed and velocity?

Back

Both speed and velocity are 0, as there is no movement.
