Speed Velocity and Acceleration Practice

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 divided by the time taken.

Front

What is velocity?

Back

Velocity is a vector quantity that refers to the speed of an object in a specific direction.

Front

What is the formula for calculating speed?

Back

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 does it mean to decelerate?

Back

Deceleration is a decrease in speed or negative acceleration.

Front

How do you measure speed?

Back

Speed is measured by dividing the distance traveled by the time taken to travel that distance.

Front

What is a common unit for measuring speed?

Back

Common units for speed include meters per second (m/s) and kilometers per hour (km/h).

Front

If a car travels 120 km in 2 hours, what is its speed?

Back

Speed = 120 km / 2 hours = 60 km/h.

Front

What is the significance of direction in velocity?

Back

Direction is crucial in velocity because it indicates where the object is moving, making it different from speed.
