Speed, Velocity & Acceleration

Front

What is the definition of 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 the definition of velocity?

Back

Velocity is the speed of an object in a specific direction, combining both magnitude and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, indicating how quickly an object is speeding up or slowing down.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the unit of measurement for distance?

Back

Meters (m) is the standard unit of measurement for distance.

Front

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

Back

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

Front

What happens when two teams pull with the same amount of force?

Back

They will not move at all.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What does it mean if an object is accelerating?

Back

It means the object is changing its speed, direction, or both.
