Speed and Velocity

Front

What is speed?

Back

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

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) north or miles per hour (mph) west.

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 unit is commonly used to measure speed?

Back

Miles per hour (mph) or meters per second (m/s) are commonly used units for measuring speed.

Front

What does 'standing still' mean in terms of speed and velocity?

Back

Standing still means that an object has a speed of 0 and is not changing its position over time.

Front

If a car travels 60 miles in 1 hour, what is its speed?

Back

The speed of the car is 60 mph.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken: Speed = Distance / Time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, indicating how quickly it is speeding up or slowing down.

Front

What is a scalar quantity?

Back

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

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity or force.
