Speed, Velocity, Acceleration

Front

What is speed?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can involve speeding up, slowing down, or changing direction.

Front

What two factors does velocity depend on?

Back

Velocity depends on speed and direction.

Front

What two factors does speed depend on?

Back

Speed depends on distance and time.

Front

Is a car driving 55 miles per hour south an example of speed or velocity?

Back

This is an example of velocity because it includes both speed and direction.

Front

If a train is traveling North at 220 km/hr, is this speed or velocity?

Back

This is velocity because it specifies a direction.

Front

What happens to the acceleration of an object if it is moving at a constant speed in a straight line?

Back

The acceleration is zero because there is no change in velocity.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.
