Calculating Speed, Velocity, and Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically expressed in miles per hour (mph) or meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

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 is a vector quantity that includes both speed and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, typically expressed in meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

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

Front

If a car's velocity changes from 20 m/s to 50 m/s in 10 seconds, what is its acceleration?

Back

3 m/s².

Front

What is the formula to calculate distance when speed and time are known?

Back

Distance = Speed x Time.

Front

If a cyclist travels at a speed of 12 km/h for 3 hours, how far do they travel?

Back

36 km.
