What is the difference between kinetic and potential energy give examples of each?
Objects can have stored, or potential, energy when work has been done (such as raising an object in the air) or by virtue of their position (such as sitting at the top of a hill). Potential energy changes to kinetic energy when the object moves. Kinetic energy is a form of energy that results from an object’s motion.
What are the relationships between kinetic energy and potential energy quizlet?
What is the relationship between potential energy and kinetic energy? Potential and kinetic energy have an opposite relationship. As kinetic energy increases, potential energy decreases. As potential energy increases, kinetic energy decreases (looking at pHet activity).
Which of the following is the best example of kinetic energy being transformed into potential energy?
Explanation: Coasting down the hill on a bicycle is a typical example of how kinetic energy is being transformed to potential energy in a system.
Why does kinetic energy depend on mass and speed?
Kinetic energy is the energy an object has because of its motion. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed. The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.
What is the importance of point A in determining the movement of the objects?
Answer: A reference point is important in determining motion because in order to say that something is moving, you need to have something stationary to compare it to. You can then define the velocity of a particle as the rate of change of the displacement of the particle from the reference point.
What force is needed to keep an object moving through space?
friction
Do force and mass have direct relationships?
Newton’s second law shows that there is a direct relationship between force and acceleration. The greater the force that is applied to an object of a given mass, the more the object will accelerate. The greater the mass of an object, the less it will accelerate when a given force is applied.
