Speed, Velocity, and Acceleration

Front

What is the formula to calculate average speed?

Back

Average speed = Total distance / Total time

Front

If a car travels 224 miles in 4 hours, what is its average speed?

Back

56 miles per hour

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

How is velocity different from speed?

Back

Velocity includes direction, while speed does not.

Front

What is the unit of acceleration?

Back

Meters per second squared (m/s²)

Front

What does it mean if an object has a constant speed?

Back

It means the object covers equal distances in equal intervals of time.

Front

What is the definition of velocity?

Back

Velocity is speed in a given direction.

Front

If a runner increases their speed from 5 m/s to 10 m/s, what is their acceleration?

Back

Acceleration = (Final speed - Initial speed) / Time taken.

Front

What is the difference between instantaneous speed and average speed?

Back

Instantaneous speed is the speed at a specific moment, while average speed is total distance divided by total time.

Front

What is a common unit for measuring speed?

Back

Miles per hour (mph) or meters per second (m/s)
