Acceleration Calculations

Front

What is acceleration?

Back

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

Front

How do you calculate acceleration?

Back

Acceleration (a) is 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

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

If a car's velocity decreases from 83 m/s to 33 m/s in 4 seconds, what is the acceleration?

Back

The acceleration is -12.5 m/s².

Front

If Nyla slows down from 56 miles/hour to 6 miles/hour in 25 seconds, what is her acceleration?

Back

The acceleration is -2 m/s².

Front

What is the acceleration of Billy's car if it slows from 190 m/s to 12 m/s in 20 seconds?

Back

The acceleration is -8.9 m/s².

Front

How do you interpret a positive acceleration?

Back

A positive acceleration means that the object is speeding up.

Front

What is the acceleration of a motorcycle that increases speed from 25 m/s to 55 m/s in 10 seconds?

Back

The acceleration is 3 m/s².

Front

If John Cena's speed increases from 15 m/s to 25 m/s over 5 seconds, what is his acceleration?

Back

The acceleration is 2 m/s².
