Acceleration

Front

What is acceleration?

Back

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

Front

What are the units of acceleration?

Back

Common units of acceleration include m/s² (meters per second squared), km/hr² (kilometers per hour squared), and mi/hr² (miles per hour squared).

Front

Which of the following is not a correct unit of acceleration?

Back

s/m² is not a correct unit of acceleration.

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

What does the slope of a velocity vs. time graph represent?

Back

The slope of a velocity vs. time graph represents acceleration.

Front

What is the effect of constant speed on acceleration?

Back

When an object moves at a constant speed, its acceleration is zero.

Front

How can you determine if an object is accelerating from a distance vs. time graph?

Back

If the distance vs. time graph is curved, the object is accelerating.

What happens to acceleration when a jet slows down?

Back

The acceleration is negative when a jet slows down.

Front

What is the formula for calculating acceleration?

Back

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