What will happen to the kinetic energy of a body if its speed is increased?
It turns out that an object’s kinetic energy increases as the square of its speed. A car moving 40 mph has four times as much kinetic energy as one moving 20 mph, while at 60 mph a car carries nine times as much kinetic energy as at 20 mph. Thus a modest increase in speed can cause a large increase in kinetic energy.
How much kinetic energy will be affected when the speed of a body is increased by 4 times?
P is proportional to the square root of kinetic energy. Since 2 and m are considered as constants. Therefore, we can say that kinetic energy increased by four times. Therefore, when the kinetic energy increases by four times, then the moment will increase by two times.
What percentage of kinetic energy of a body will be increased if it’s velocity is increased by 3 times?
The kinetic energy of a body increases by 300\% due to change in its velocity.
How will the kinetic energy of a body change if velocity of a body is increased three times?
Kinetic energy will become 9 times .
How much will the kinetic energy of a body increase if its speed is doubled 1 point 4 times 2 times Ke will not increase?
If the speed of an object is doubled by increasing its velocity, its kinetic energy becomes four times its initial value. Thus kinetic energy increases by four times when its momentum is doubled. Hence kinetic energy of a body is increased most by doubling its speed.
What is the percentage change in kinetic energy of a body if its momentum is increased by 2\%?
2 Answers. Percentage increase in kinetic energy is 300\% .
What change should be affected in the velocity of the body to maintain same kinetic energy if its mass is increased two times?
Since Ek=12mυ2, the velocity should be reduced to half its previous value to have to have the saem kinetic energy when mass is increased to four times.
How much would the kinetic energy of an object change if it has 3 times the initial velocity?
Answer: If velocity is increased three times, then its kinetic energy becomes 9 times the original value, because it is proportional to the square of the velocity.
How much will the kinetic energy of a body?
Kinetic energy of a body is directly proportional to the square of velocity. So, the kinetic energy will become four times the initial value when velocity is doubled.
