Question

A toy car rolls down an incline and across a gravel path word sloth and eventually stops what energy transformation takes place is the car rolls across the gravel

Answer 1

The answer to the question is;

Gravitational Potential Energy → Translational Kinetic Energy + Rotational Kinetic Energy.

Step-by-step explanation:

Gravitational Potential Energy → Translational Kinetic Energy + Rotational Kinetic Energy

That is

m·g·h → 1/2·m·v²+1/2·I·ω²

Where:

m = Mass of the car

v = Linear velocity of the car

g = Acceleration due to gravity

h = Initial elevation of the car

I = Moment of inertia or rotational inertia

ω = Angular velocity =
`(v)/(r)`

By the parallel axis theorem, I, the moment of inertia about the point of contact between the tires and the gravel

Gravitational potential energy is the energy the object has due to its height while

Translational Kinetic Energy is the energy due to translational motion and rotational kinetic energy is the energy due to rotation.
