What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in kilometers per hour (km/h) or meters per second (m/s).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity.

Front

What is acceleration?

Back

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

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight line distance from the starting point to the endpoint, including direction.

Front

Can distance be negative?

Back

No, distance is always a positive value.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

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

Back

Average speed = 120 km / 2 hours = 60 km/h.

Front

What is a vector quantity?

Back

A vector quantity has both magnitude and direction, such as velocity and acceleration.

Front

What is a scalar quantity?

Back

A scalar quantity has only magnitude and no direction, such as speed and distance.
