Acceleration Practice

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v_f) - Initial Velocity (v_i)) / Time (t)

Front

If a car is speeding up, what can we say about its acceleration?

Back

The acceleration is positive.

Front

If a car is slowing down, what can we say about its acceleration?

Back

The acceleration is negative.

Front

What is the unit of acceleration in the International System of Units (SI)?

Back

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

Front

How do you convert km/hr to m/s?

Back

To convert km/hr to m/s, divide the speed by 3.6.

Front

What does a constant acceleration mean?

Back

Constant acceleration means that the rate of change of velocity is the same over time.

Front

What is the significance of a zero acceleration?

Back

Zero acceleration indicates that an object is moving at a constant velocity.

Front

Calculate the acceleration if a bike goes from 10 m/s to 20 m/s in 5 seconds.

Back

Acceleration = (20 m/s - 10 m/s) / 5 s = 2 m/s².

Front

What is the acceleration of an object that goes from rest to 30 m/s in 10 seconds?

Back

Acceleration = (30 m/s - 0 m/s) / 10 s = 3 m/s².
