examples of energy transfer

• If the object hits an obstacle, such as the car hitting a wall, the speed of the car will decrease very quickly, transferring most of the energy from its kinetic store to the thermal store of the surroundings.
• When an object, such as a car, is moving, energy in the chemical store of the fuel is transferred to the kinetic store of the car.
• When the object is thrown, some of that energy is transferred to the kinetic store of the object as it begins to move upwards.
• Energy is transferred mechanically to the thermal store of the wall when the car hits the wall, and is also transferred by heating due to friction between the tyres on the ground and due to friction between the brakes and the brake pads.
• When an object is projected upwards, the person holding the object has energy in their chemical store.
• When an electric kettle boils water, energy is transferred by electrical working from the mains to the thermal store of the heating element inside the kettle.
• As the height of the object increases, energy from the kinetic store of the object is transferred to its gravitational potential store.
• Energy changes in a system can involve different types of energy transfers, such as when an object is projected upwards, a moving object hits an obstacle, an object is accelerated by a constant force, a vehicle speeds up or slows down, water is brought to a boil in an electric kettle, or when a ball is thrown upwards.
• As the heating element gets hotter, energy is transferred by heating to the thermal store of the water.
