Speed Velocity Acceleration

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 speed?

Back

Speed is a scalar quantity that refers to how fast an object is moving, calculated as distance traveled per unit of time.

Front

What is velocity?

Back

Velocity is a vector quantity that includes both the speed of an object and the direction of its motion.

Front

How is speed calculated?

Back

Speed is calculated using the formula: Speed = Distance / 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 happens to acceleration when an object is moving at a constant speed?

Back

When an object is moving at a constant speed, its acceleration is zero.

Front

What is an example of negative acceleration?

Back

An example of negative acceleration is a car slowing down as it approaches a stop sign.

Front

What unit is commonly used to measure speed?

Back

Speed is commonly measured in meters per second (m/s) or kilometers per hour (km/h).

Front

What is the formula for calculating distance?

Back

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

Front

What is the significance of direction in velocity?

Back

Direction is significant in velocity because it determines the object's path and can change even if speed remains constant.
