Topic 6: Hotwheels


Energy is the capacity to do work

Kinetic energy  of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.

Potential energy is the energy that is stored in an object due to its position relative to some zero position.

What was the point of this activity?

The point of this activity was to help students understand potential and kinetic energy and how motion plays a part in all of that.

Explain how you would introduce this to your class?

I would introduce this to my class asking what they observe about the race track and what this would have to do pertaining  to science. Then ask what they knew about potential and kinetic energy.

Where do you see a student having difficulty with this?

I could see students struggle with measuring the height accurately. They may bend the two sides which can skew results.

What changes or extensions could you do to this activity?

I would add more sides to the to see if it affects how the car goes through the loop. I would then ask them how that would affect the potential and kinetic energy.
