Speed, Velocity, Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in units like miles per hour (mph) or kilometers per hour (km/h).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

Front

What is the formula for calculating time?

Back

Time = Distance / Speed.

Front

If a car travels 60 miles in 1 hour, what is its speed?

Back

60 miles per hour (mph).

Front

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

Back

36 kilometers.

Front

What happens to the velocity of an object moving in a circular path?

Back

The velocity changes because the direction of the object is constantly changing, even if the speed remains constant.

Front

What is a unit of acceleration?

Back

Meters per second squared (m/s²).
