speed and velocity

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.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).

Front

What is average speed?

Back

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

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What does acceleration mean?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (final velocity - initial velocity) / time.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude, 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.
