Everything that moves has kinetic energy. The wind causing things such as leaves and branches to move and moving water are two examples of kinetic energy for kids.Continue Reading
Energy in motion is the basic definition of kinetic energy. The more an object weighs, the more kinetic energy said object has. A good example for children is to use two balls that have different weights. Place the balls on the table and roll them off into a bowl of water that is placed on the floor. When they fall, the ball that is heavier will make a bigger splash compared to the lesser weighted ball, and this means the heavier ball has more kinetic energy.
Another type of energy is called potential energy. This energy includes things that are stored such as oil, gasoline and coal. In a car, energy can change from kinetic energy to potential energy, and then back to kinetic energy again. When the car is in motion, it is kinetic energy. When the car stops, it turns into potential energy.
Mechanical energy is energy of motion like that of a windmill. Heat energy is the energy in motion that raises the temperature; a fire in a fireplace is a good example. Chemical energy is stored in things like food and fuel, while the electric coils in a stove create electrical energy.Learn more about Motion & Mechanics
Helpful examples of motion for children include pushing toy cars; throwing dodgeballs, baseballs or footballs; dropping bowling balls; and throwing paper airplanes. Because force is connected to motion, various levels of force applied to these motion examples shows how differences in force contribute to differences in motion.Full Answer >
As a reference to a perpetual motion machine, a continuous motion machine is one that continues to operate indefinitely without the application of energy or force as an input. Such machines defy the laws of physics and do not exist in the conditions on Earth due to forces such as gravity and friction.Full Answer >
Energy of motion is the energy an object possesses due to its motion, which is also called kinetic energy. This means that the object, which has energy of motion, can do work on any object it hits.Full Answer >
Making a can that "magically" rolls back toward the person who sent it away and designing a roller coaster track for marbles are two science projects displaying kinetic energy. Kinetic energy is the type of energy that is expressed in movement, either of a body or of a system's particles.Full Answer >
