What happens to the kinetic energy store when an object slows down?
The object’s energy is slowly transferred from the kinetic store to the gravitational potential store as it slows down and climbs higher. Once the object reaches its highest point, all of its energy is in the gravitational potential store. During this process, energy is dissipated (lost) through heat and sound.
What increases the kinetic energy of an object?
If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. The word “kinetic” comes from the Greek word “kinesis” which means motion. Kinetic energy can be passed from one object to another in the form of a collision.
What factor can decrease the kinetic energy of an object?
velocity
What does the inertia of a moving object depend on?
The inertia of a moving object depends on the mass of the object. Heavier the item, the Heavier is its tendency to resist the change in state of motion.
Will the kinetic energy of an object depends on the speed of the observer?
Answer: Explanation: kinetic energy depends upon the frame of reference (in your question it is the speed of the observer). since kinetic energy is directly proportional to velocity so same is the case with kinetic energy.
On what factors does the kinetic energy of a body depend?
The kinetic energy of a body or object depends upon its velocity and mass.
How much will the kinetic energy of a body increase if its speed is doubled?
1 Answer. Kinetic energy of a body depends on its mass and its speed. Hence, ,kinetic energy will become 4 times the original kinetic energy if the speed is doubled.
How fast should a man of 50kg run so that his kinetic energy be 625j?
v=5m/s.
How fast should a man of 50kg run so that is kinetic energy is 625 Joule?
So , the man should be running with a speed of 5 m/s .
How fast should a man of mass 60 kg run so that is kinetic energy is 750 Joule?
15m/s.
How fast a man of mass 80 kg should run so that his kinetic energy is 750 J?
Answer. So,the man have to run at the rate of 5 metres per second.
How fast can a man weighing 600n run to achieve a kinetic energy of 750 J?
5ms−1.
How will the momentum of body change if its kinetic energy is doubled?
Because momentum is directly proportional to the speed as well as mass, doubling the kinetic energy by changing the speed will increase the momentum by a factor , or make it times larger.
