Speed, Velocity, Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in 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 can occur due to a change in speed or direction.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the unit of speed?

Back

Common units of speed include kilometers per hour (km/h) and miles per hour (mph).

Front

What is the unit of distance?

Back

Common units of distance include kilometers (km), miles, and meters (m).

Front

If a car travels 300 miles in 5 hours, what is its speed?

Back

Speed = 300 miles / 5 hours = 60 mph.

Front

What happens to the speed of an object if it accelerates?

Back

If an object accelerates, its speed increases over time.

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 uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate.
