What happens to the kinetic energy when the speed is tripled?

If the speed triples, how does the kinetic energy change? The kinetic energy increases as the square of the speed. If the speed triples, how does the kinetic energy change? The kinetic energy increases by a factor of 9.

What happens to the kinetic energy of an object if the speed is doubled?

The kinetic energy is proportional to the square of the speed, so doubling the speed increases the kinetic energy by a factor of 4. However, doubling the speed does double the momentum, which we will cover in the next unit.

How much will the kinetic energy of a body increase if its speed is tripled?

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 happens to the kinetic energy when the mass is tripled and the speed is tripled?

1 Expert Answer a)So if the mass triples then the KE triples too. The relationship between Kinetic Energy and velocity is also directly proportional but with the square of the velocity. b) So if the velocity triples, then it is 32 , three squared or 9. Hence, KE is 9 times greater.

Which of the following when tripled has the greatest effect on kinetic energy?

Therefore, doubling the velocity has greater effect on the kinetic energy of the object than doubling its mass. Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy.

What factors affect the kinetic energy answer?

The two main factors that affect kinetic energy are mass and speed. Why? Because the motion of an object depends on how fast it’s traveling, but also how much mass it has, though velocity is the more important factor.

What are the factors that affect kinetic energy?

1. Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed. Have students complete this demonstration to learn how mass influences an object’s kinetic energy.

On what factor does the kinetic energy of a body depend?

Thus the kinetic energy of a body or object depends upon its velocity and mass.

How would the kinetic energy of a moving object change if its velocity is increased to 3 times its original amount?

This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine.

What factor has the greatest effect on kinetic energy?

What two factors affect kinetic energy?

Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed.

What factor s affect s the kinetic energy of an object?
