Speed, Velocity, and Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or miles per hour (mph).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, expressed in units like meters per second (m/s) east.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time, measured in meters per second squared (m/s²).

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the formula for calculating velocity?

Back

Velocity = Displacement / 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 does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.

Front

What does a negative acceleration indicate?

Back

A negative acceleration (deceleration) indicates that an object is slowing down.

Front

If a car travels 120 miles in 2 hours, what is its average speed?

Back

Average speed = 120 miles / 2 hours = 60 miles per hour.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).
