Chapter 15- Science
| Question | Answer |
|---|---|
| What type of energy is: a car driving on a flat road? | Kinetic Energy |
| What type of energy is: a descending roller coaster? | Both |
| What type of energy is: a stationary wind-up toy with a compressed spring? | Potential Energy |
What is the energy conversion when a wind-up toy is set in motion?
Because the moving wind has mechanical energy (in the form of kinetic energy), it is able to do work on the blades.
Is the following true or false energy can be converted from one form to another?
First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another.
When energy is converted from one form to another A what has occurred?
The law of conservation of energy states that when one form of energy is transformed to another, no energy is destroyed in the process. According to the law of conservation of energy, energy cannot be created or destroyed. So the total amount of energy is the same before and after any transformation.
What kind of energy is a wind up car?
When you wind up the car’s axle you stretch the rubber band and store potential energy. When you release it the rubber band starts to unwind, and the potential energy is converted to kinetic energy as the car is propelled forward.
What type of energy does a wind up toy that is not wound up have?
mechanical energy
The energy associated with the motion and position of an object is mechanical energy. 6. The drawing shows a wind-up toy.
Is a wind up toy mechanical energy?
The energy associated with the motion and position of an object is mechanical energy. 6. The drawing shows a wind-up toy. most forms of energy can be transformed into other forms.
What energy is in a toy car?
Toy cars use a variety of mechanisms to make them go, but they all store up potential energy. Although the elastic material inside is usually steel and not rubber, the principle is the same. By changing the shape of the material (usually a coil of metal) energy is stored and then released as motion.
Is energy matter true or false?
Explanation: Matter is anything which occupies space and has mass . But energy doesn’t have mass and also not occupy space .
When potential energy is used it is converted into kinetic energy?
If we drop the object from the shelf or release the spring, that potential energy is converted back into kinetic energy. Kinetic energy can also be transferred from one body to another in a collision, which can be elastic or inelastic. One example of an elastic collision would be one billiard ball striking another.
What happens when a wind up toy is released?
When a wind-up toy is released, the energy in the compressed spring is converted into the _____ energy of the toy’s moving parts. The answer is kinetic energy. Did this page answer your question? Still have questions?
What kind of energy is a mechanical Changle?
For a mechanical changle in an isolated system, the mechanical energy at the beginning equals the mechanical energy at the end of the process, as long as the friction is negligible. True. What type of energy is it? A stationary wind-up toy with compressed spring. Potential. What type of energy is it? A descending rollercoaster car.
When does mechanical energy equal at the beginning?
For a mechanical change in an isolated system, the mechanical energy at the beginning equals the mechanical energy at the end of the process, as long as friction is negligible. What is the form of energy? What is the form of energy? What is the form of energy? What is the form of energy? What is the form of energy?
What happens to the energy of an object when it slows down?
When an object slows down because of frictional force acting on it, an amount of energy is destroyed that is equivalent to the decrease in kinectic energy of the object. False. Thermal energy. Kinetic energy.
