What happens to an objects kinetic energy as its mass increases?
kinetic energy, K.E = 1/2 mv^2 that is, it is directly proportional to mass, assuming velocity to be constant and is directly proportional to square of velocity assuming mass to be constant.
Does mass or speed effect more on kinetic energy?
Kinetic energy = 0.5 x mass x velocity^2. Your answer should be velocity.
How does increasing mass effects kinetic energy?
Increasing mass increases kinetic energy. The formula for KE = 1/2mv2, where m is mass in kg and v is velocity in m/s. KE is directly proportional to both mass and velocity, so if either one increases, so does the KE.
How does velocity have an effect on kinetic energy?
The summation of potential and kinetic energy of an object is constant. When the potential energy of an object decreases the kinetic energy increases. Assume a falling stone from some high point above ground. At the beginning, the potential energy is maximum while the kinetic energy is minimum or zero. While the stone is falling, the kinetic energy increases while the potential energy increases (with the summation of both is constant). When the stone reaches the ground, the kinetic energy is maximum and the potential energy is zero.
What 2 factors effect an object's of kenetic energy?
Kinetic energy is (1/2) x mass x velocity2.Kinetic energy is (1/2) x mass x velocity2.Kinetic energy is (1/2) x mass x velocity2.Kinetic energy is (1/2) x mass x velocity2.
What is inertia in a 3 Phase motor?
A motor when running has inertia in the rotating parts, which is a reserve of kinetic energy. The kinetic energy is found as the moment of inertia times the square of the angular velocity.
Quantity that remains constant during uniform circular motion?
-- tangential speed -- angular velocity -- kinetic energy -- magnitude of momentum -- radius of the circle -- centripetal acceleration
Why is it easier to determine the coefficient of kinetic friction if the object moves with a constant velocity?
if moving with constant velocity the only force to slow it down is kinetic friction; if it is accelerating velocity is not constant and an additional force is being applied.
What happens to an objects kinetic energy as its mass increases?
kinetic energy, K.E = 1/2 mv^2 that is, it is directly proportional to mass, assuming velocity to be constant and is directly proportional to square of velocity assuming mass to be constant.
What is the nature of graph between kinetic energy and mass when velocity is constant?
The graph is linear.
Why does a skater angular velocity increase when putting their arms in?
the equation for rotational kinetic energy (KE) is:.KE = 0.5 * I * ((rad / sec)^2), where I is the mass moment of inertia..so if the kinetic energy remains constant, the only thing that can alter the rotation rate (rad / sec), is I, the mass moment of inertia
If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
What happens when kinetic energy is absorbed as an object moves toward the earth?
The kinetic energy increases as the velocity increases (KE = 1/2mv2) until terminal velocity is reached, at which point the velocity becomes constant, and kinetic energy will no longer increase. The potential energy and kinetic energy will be at equilibrium, where PE = -KE.
When the speed of body is doubled kinetic energy becomes?
If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.
Does mass or speed effect more on kinetic energy?
Kinetic energy = 0.5 x mass x velocity^2. Your answer should be velocity.
Which one of the following remains constant while throwing a ball upward-displacement or kinetic energy or acceleration or velocity?
displacement
What does v stand for in the formula of kinetic energy?
The v in the formula for density stands for volume.
