Grade 10 Mathematics Teachers’ Book

Use the slider labeled “Initial velocity” to set the starting speed of the car.

Use the slider labeled “Acceleration” to control how quickly the car’s speed changes.

Click Start to begin the animation.

Observe the arrow above the car. This arrow represents the velocity of the car and changes length as the speed increases.

Watch the dotted line and the label above the car to see how the distance traveled changes with time.

Click Pause at any time to examine the car’s position, velocity, and time.

Click Resume to continue the motion.

Click Reset to restart the simulation and try a different combination of initial velocity and acceleration.

Set the acceleration to \(0\text{.}\) Start the animation. How does the car move when there is no acceleration? What happens to the velocity arrow?

Keep the initial velocity the same but increase the acceleration. How does the speed of the car change over time?

Pause the animation after a few seconds. Compare the values of velocity, time, and position. How does acceleration influence how quickly the velocity increases?

Try a larger acceleration value. How does this affect how quickly the car moves across the screen?

Based on your observations, explain why the distance traveled by the car depends on both the initial velocity and the acceleration.
