Acceleration

Front

What is Acceleration?

Back

A change in Motion.

Front

What is the metric unit for acceleration?

Back

m/s²

Front

How do you calculate acceleration?

Back

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

Front

If a roller coaster accelerates from 6.0 m/s to 70 m/s in 4 seconds, what is the acceleration?

Back

16 m/s².

Front

A car starts from rest and reaches 20 m/s in 3.5 seconds. What is the acceleration?

Back

5.7 m/s².

Front

What does a negative acceleration indicate?

Back

The object is slowing down.

Front

What is the formula for final velocity?

Back

V_f = (a • t) + v_i.

Front

If a car is traveling at 30 m/s and decelerates at -6.25 m/s², how long will it take to stop?

Back

Use the equation: t = (v_f - v_i) / a.

Front

What is the difference between speed and acceleration?

Back

Speed is how fast an object is moving, while acceleration is the rate of change of velocity.

Front

What is uniform acceleration?

Back

Acceleration that is constant over time.
