Speed and Velocity Flashcard

Front

What is velocity?

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position. It includes both speed and direction.

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 includes both the speed and the direction of the object's movement.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude but no direction, such as temperature or mass.

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.

Front

How do you calculate distance traveled?

Back

Distance traveled can be calculated using the formula: Distance = Speed × Time.

Front

If a car travels at a speed of 60 km/h for 2 hours, how far does it travel?

Back

Distance = Speed × Time = 60 km/h × 2 h = 120 km.

Front

What is the unit of velocity?

Back

The unit of velocity is typically meters per second (m/s) or kilometers per hour (km/h).

Front

What does it mean if an object has a constant velocity?

Back

An object has a constant velocity if it is moving at a constant speed in a straight line, meaning its speed and direction do not change.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

What is the formula for calculating acceleration?

Back

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