When a spring is compressed the energy changes from kinetic to potential which best?
Answer. when spring is compressed his rings will shrink and store a energy known as kinetic energy. when it relaxes the kinetic energy converted into potential energy because the energy is produced by the motion of the springs.
When a spring is compressed the energy changes from kinetic energy to potential?
Explanation: When a spring is compressed the energy changes from kinetic to potential energy as Energy cannot be destroyed but can be transformed from one form to another. This can be best explained with the help of work.
Which best describes a joule?
One joule is defined as the amount of energy exerted when a force of one newton is applied over a displacement of one meter. One joule is the equivalent of one watt of power radiated or dissipated for one second. In some applications, the British thermal unit (Btu) is used to express energy.
Which best defines energy?
Energy is the ability to do work. Energy is the rate at which work is done. Energy is the motion of objects.
What are different forms of energy?
The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.
How does energy transfer work?
To do work requires that an agent exert a force on an object over a distance. When work is done, energy is transferred from the agent to the object, which results in a change in the object’s motion (more specifically, a change in the object’s kinetic energy).
How does energy cause changes?
HOW DOES ENERGY CHANGE FORM? When something happens, energy is changed from one form into another. When you climb stairs, chemical energy in your food is changed into kinetic energy by your muscles, and into potential energy as you raise your body against gravity. The amount of energy transferred is measured in JOULES.
Which type of energy is associated with position?
mechanical energy
Does energy have the ability change?
Energy is the ability to do work or to produce change. Energy is transferred from one object to another when work is done. Kinetic energy is the energy that an object has because of its motion.
How is energy and motion related?
Kinetic energy is the energy of motion. All moving objects have kinetic energy. When an object is in motion, it changes its position by moving in a direction: up, down, forward, or backward. As he winds up and releases the ball, the stored energy is changed into kinetic energy, the energy of motion!
What is the original source of most energy used on earth?
the sun
What is force give one example?
A force involves an interaction between two or more objects, and it causes a push or pull between the objects. Good examples of opposing force include drag due to interaction with an air mass and the force due to friction between two objects.
What are the 4 kinds of friction?
There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces.
Which friction of the following is the highest?
The maximum value of static friction is called limiting friction.
What are the two effects of friction explain with examples?
Effects of Friction It produces heat, that helps in heating parts of any object or to warm ourselves. It also causes loss in power. It produces noise during any kind of operation. It’s because of friction that we’re able to walk, run, play, etc.
