Acceleration Practice

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be positive (speeding up) or negative (slowing down).

Front

How do you calculate acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the unit of acceleration?

Back

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

Front

If a sprinter goes from 5 m/s to 40 m/s in 10 seconds, what is the acceleration?

Back

3.5 m/s².

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

What is the acceleration of an object that goes from rest to 40 m/s in 4 seconds?

Back

10 m/s².

Front

How do you interpret acceleration in a real-world context?

Back

Acceleration can describe how quickly a vehicle speeds up or slows down, affecting travel time and safety.

Front

What is the acceleration of a drag racer that goes from 0 m/s to 200 m/s in 5 seconds?

Back

40 m/s².

Front

What is the acceleration of a roller coaster that speeds up from 6.0 m/s to 70 m/s in 4 seconds?

Back

16 m/s².

Front

If a bicyclist decreases speed from 10 m/s to 6 m/s in 2 seconds, what is the acceleration?

Back

-2 m/s².
