Speed, Velocity, and Acceleration

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, e.g., 500 mph West.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to a change in speed or direction.

Front

If a bike travels at a constant speed of 10 km/h, what can be said about its acceleration?

Back

Acceleration did not occur because neither speed nor direction changed.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating acceleration?

Back

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

Front

Calculate the speed of a rocket that travels 9000 meters in 12.12 seconds.

Back

742.57 m/s.

Front

Calculate the speed of a jet plane that travels 528 meters in 4 seconds.

Back

132 m/s.

Front

How long will your trip take if you travel 350 km at an average speed of 80 km/h?

Back

4.38 hours.

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).
