RP 2-2 Acceleration and Graphs

Front

What is the unit for acceleration?

Back

(m/s²)

Front

What does negative acceleration indicate about an object's motion?

Back

The object is slowing down.

Front

If a car accelerates from a stop to 70 m/s in 10 seconds, what is the acceleration?

Back

7 m/s²

Front

A box sliding down an inclined plane attains a velocity of 27 m/s in 3 seconds from rest. What is the acceleration?

Back

9 m/s²

Front

What does a distance vs. time graph showing a straight horizontal line indicate?

Back

The object is moving at a constant speed.

Front

Define acceleration.

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What does it mean if an object has zero acceleration?

Back

The object is either at rest or moving at a constant speed.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is a common example of negative acceleration in everyday life?

Back

A car slowing down as it approaches a stop sign.
