Calculating Acceleration

Front

What is the SI unit for acceleration?

Back

m/s²

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

If a car's speed changes from 20 m/s to 50 m/s in 10 seconds, what is its acceleration?

Back

3 m/s²

Front

What does a negative acceleration indicate?

Back

It indicates deceleration or slowing down.

Front

If a cyclist accelerates from rest to 10 m/s in 5 seconds, what is the acceleration?

Back

2 m/s²

Front

What is the formula for calculating acceleration?

Back

a = (v_f - v_i) / t, where v_f is final velocity, v_i is initial velocity, and t is time.

What is the acceleration of an object that goes from 30 m/s to 0 m/s in 6 seconds?

Back

-5 m/s²

Front

If a runner speeds up from 5 m/s to 15 m/s in 2 seconds, what is the acceleration?

Back

5 m/s²

Front

What is the acceleration of a car that goes from 10 m/s to 40 m/s in 15 seconds?

Back

2 m/s²

Front

What does it mean if an object has an acceleration of 0?

Back

It means the object is moving at a constant speed.
