Question

A car is driving on a level road (height, h = 0 meters) at a speed, v.a.It has Potential Energy due to its height (PE = mgh)b.It has Potential Energy because someone left a burrito on the seat.c.It has Kinetic Energy due to its height (KE = mgh)d.It has Kinetic Energy due to its motion (KE = 1/2 mv²)

Answer 1

d. It has Kinetic Energy due to its motion (KE = 1/2 mv²)

Step-by-step explanation:

The potential energy can be calculated as

PE = mgh

Where m is the mass, g is the gravity and h is the height, so there is potential energy when there is height.

The kinetic energy can be calculated as

KE = 1/2 mv²

Where m is the mass and v is the speed, so the kinetic energy depends on the speed.

In this case, the car has no height but it has speed, which means that there is kinetic energy. So, the answer is

d. It has Kinetic Energy due to its motion (KE = 1/2 mv²)
