Understanding Uniform Acceleration

What is uniform acceleration?

• A constant change in velocity over time

• A constant speed over time

• A change in direction over time

• A change in velocity at irregular intervals

What does a position-time graph look like for an object with uniform acceleration?

• A straight line

• A curve

• A zigzag line

• A horizontal line

On a velocity-time graph, what does the slope of the line represent for an object with uniform acceleration?

• The rate of acceleration

• The initial velocity

• The final velocity

• The total distance traveled

Which of the following is an example of uniform acceleration in everyday life?

• A ball rolling down a hill

• A car stopping at a traffic light

• A person walking at a constant speed

• A plane taking off

Why are experiments with ramps and toy cars useful in understanding uniform acceleration?

• They help connect theoretical concepts with real-world experiences

• They demonstrate how to build ramps

• They show how to stop a moving object

• They illustrate how to change an object's color
