Speed, Velocity and Acceleration Flashcard

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is calculated using the formula: Velocity = Distance / Time, and it includes direction.

Front

What do you need to calculate velocity?

Back

To calculate velocity, you need distance, time, and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is calculated using the formula: Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

If a sledder goes from 2 m/s to 12 m/s in 5 seconds, what is the acceleration?

Back

The acceleration is 2 m/s².

A cyclist increases her speed from 5 m/s to 14 m/s in 3 seconds. What is her acceleration?

Back

Her acceleration is 3 m/s².

What is the average speed of a student who travels 30 m in 40 s?

Back

The average speed is 0.75 m/s.

Front

George rides his scooter 32 m in 20 s. What is his speed?

Back

His speed is 1.6 m/s.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude only and no direction, such as speed or distance.
