Exploring Notation and Negative Acceleration

What is the formula for acceleration?

• Change in position over change in time

• Change in velocity over change in time

• Velocity times time

• Position divided by time

Which of the following is a scalar quantity?

• Delta V

• Time

• Acceleration

• Velocity

What does 1 m/s² represent?

• 1 meter per second squared

• 1 meter per second per second

• 1 meter per second cubed

• 1 meter per second

How does velocity change with constant acceleration?

• It fluctuates

• It decreases

• It increases

• It remains the same

If acceleration is 1 m/s², what will be the velocity after 3 seconds if it started at 1 m/s?

• 4 m/s

• 3 m/s

• 5 m/s

• 2 m/s

What happens to velocity when acceleration is negative?

• It becomes zero

• It remains constant

• It decreases

• It increases

What is the effect of negative acceleration on a position vs. time graph?

• The slope remains constant

• The slope increases

• The slope decreases

• The slope becomes zero

In physics, how is deceleration treated?

• As negative acceleration

• As positive acceleration

• As zero acceleration

• As a separate concept from acceleration

What happens when acceleration and velocity have the same sign?

• The object remains at constant speed

• The object speeds up

• The object stops

• The object slows down
