Motion, Speed, and Velocity

Front

What is motion?

Back

Motion is the process of changing position.

Front

What is speed?

Back

Speed is the distance an object moves in a unit of time.

Front

What is velocity?

Back

Velocity is speed in a specific direction.

Front

Front

What unit is commonly used to measure speed?

Back

Kilometers per hour (km/hr) or meters per second (m/s).

Front

If a car travels 100 km in 2 hours, what is its speed?

Back

Speed = 100 km / 2 hr = 50 km/hr.

Front

What does it mean if an object is at rest?

Back

An object is at rest if it is not changing its position relative to a reference point.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.
