Why is kinetic energy at its lowest at the top of the swing?
Why is kinetic energy at its lowest at the top of the swing?
At the bottom of its swing, the bob’s kinetic energy is at a maximum and its gravitational potential energy is at a minimum – because it is at its lowest point. As the bob swings upwards it slows down. Its kinetic energy decreases as work is done against its weight. At the very top of its swing it stops for a moment.
What type of energy is fruit?
Fruit are a fantastic energy source. Sweet and juicy, they are full of natural sugars, that are broken down quickly into glucose, which the body then uses as a quick energy source. In this article I take a look at 4 fruits that can help boost your energy levels and the best way to add them to your diet.
Why are apples high in potential energy?
Gravitational potential energy is the energy that an object or system has due to the force of gravity. An apple hanging from a tree branch has gravitational potential energy relative to the earth, because it has mass and is located at a distance from the earth’s surface.
What happens when an apple hits the ground?
When an apple falls from the tree to the ground, its energy of position (stored as gravitational potential energy) is converted to kinetic energy, the energy of motion, as it falls. When the apple hits the ground, kinetic energy is transformed into heat energy.
What force brings the apple down?
An apple hanging on a tree is acted upon by two basic forces: 1) the downward force exerted by the gravity force and, 2) the upward force exerted by the tree limb. The downward gravity force is also know as “weight”.
Can a pendulum swing forever?
No pendulum can swing forever because the system loses energy on account of friction. That’s why a grandfather clock has to be rewound every few days, to inject a little energy back into the system.
Why are apples better than coffee?
Apples contain no caffeine but instead have about 13 grams of natural sugar. These sugars provoke a similar response to caffeine because vitamins from the apple are released slowly throughout the body, making you feel more awake. Unlike caffeine, there are no jolts, mood swings, anxiety, jitters or the dreaded crash.
What does the apple doesn’t fall far from the tree?
The apple doesn’t fall far from the tree is a phrase that is typically said in connection with children who show qualities or talents that are similar to those of their parents.
What will happens to an apple that falls freely?
