2. Identify five more types of energy transformations that you see at home, at school, or outdoors. Make sure to name the action, such as turning on a light, as well as the two types of energy involved. Remember, for energy to be transformed, the type of energy before and after a task must be different. (10 points) As you look around you, make note of technology that is turned on and off. This indicates that some sort of energy is present before the switch is flipped. Also look at objects that move from one height to another, because that will involve kinetic and gravitational potential energy. Finally, look for actions that involve changes in temperature, sound, and light. Often these actions mean that energy is being transformed.

Explanation:

Energy is the capacity to do work. It exist in various forms which can be converted or transformed from one form into another. Examples of energy transformations are:

1. Turning on a light with the switch. (Electrical energy is transformed into light energy)

2. Lighting of a gas cooker. (Chemical energy is converted to heat and light energy)

3. Throwing a stone from a height to the ground. (The kinetic energy of the stone is converted to sound, heat and gravitational potential energy)

4. Turning on an electrical fan. (Electrical energy is converted to mechanical and sound energy)

5. Blaring of siren of an ambulance. (Electrical energy is converted to sound energy)

grav potential energy

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is
