Answer:

As the marble starts rolling down the roller coaster, the amount of potential energy stored in the marble decreases while its kinetic energy increases. Potential energy is also converted into heat energy due to friction.

Explanation:

As the marble rolls down the hill its potential energy is converted to kinetic energy (its height decreases, but its velocity increases). When the marble goes back up the loop its height increases again and its velocity decreases, changing kinetic energy into potential energy.

The two (2) ways in which the potential energy of a marble on a ramp can be increased are:

I. By placing the marble higher on the ramp.

II. By increasing the mass of the marble.

Potential energy can be defined as a type of energy possessed by an object (body) as a result of its position (height) above the earth.

Mathematically, potential energy (P.E) is calculated by using the following formula:

[tex]P.E = mgh[/tex]

Where:

  • m is the mass of an object.
  • g is the acceleration due to gravity.
  • h is the height of an object.

Hence, potential energy (P.E) is highly dependent on two (2) main factors and these are:

1. Height above the ground.

2. The mass of an object.

In conclusion, the two (2) ways in which the potential energy of a marble on a ramp can be increased are:

  • Increasing the height of the marble, by placing the marble higher on the ramp.
  • By increasing the mass of the marble such as adding more marbles.
