The Kinetic Energy Ek of an object depends on both its mass m and its speed v.
Example of kinetic energy problem. Any moving object has kinetic energy and KE energy must be removed from the object to slow it down eg. Energy Work Power 2 of 31 Kinetic Energy Example No. Windmills form one of the good examples of applications of kinetic energy.
In a windmill when the wind. Friction transforms kinetic energy of the suitcase into thermal energy. Assume that friction can be ignored Solution.
The kinetic energy of the mass is given by. Stationary objects have no kinetic energy. Calculate the kinetic energy of the car.
Underneath are questions on Kinetic energy which aids one to understand where they can use these questions. A car with a mass of 700 kg is moving with a speed of 20ms. Suppose a car has 3000 Joules of kinetic energy.
A lump of ice falls from an aeroplane as it comes in to land. M 150kg v 15ms KE ½ 150kg 15 ms2 KE ½ 150kg225 KE 16875J 2. Compute its Kinetic energy.
Will they have same speed. No energy is lost. What will be its kinetic energy if the speed is doubled.
