Unit 2 Motion Test

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can occur when an object speeds up, slows down, or changes direction.

Front

List three ways an object can accelerate.

Back

1. Speeding up 2. Slowing down 3. Changing direction

Front

What does a velocity vs. time graph represent?

Back

A velocity vs. time graph shows how the velocity of an object changes over time.

Front

What is positive acceleration?

Back

Positive acceleration occurs when an object increases its speed.

Front

What is negative acceleration?

Back

Negative acceleration, also known as deceleration, occurs when an object decreases its speed.

Front

How can you determine acceleration from a graph?

Back

Acceleration can be determined by the slope of the velocity vs. time graph. A steeper slope indicates greater acceleration.

Front

What does a flat line on a velocity vs. time graph indicate?

Back

A flat line indicates that the object is moving at a constant velocity, meaning there is no acceleration.

Front

What is the significance of the area under a velocity vs. time graph?

Back

The area under the graph represents the distance traveled by the object during that time interval.

Front

What does it mean if an object has zero acceleration?

Back

Zero acceleration means that the object's velocity is constant; it is neither speeding up nor slowing down.

Front

What is the formula for acceleration?

Back

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