A disc weighing 2 kg rolls without slipping over a horizontal plane with a velocity 4 ms1 Find the kinetic energy of the disc?
Kinetic energy is proportional to the square of the magnitude of velocity.
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4
The object has a mass of 2kg. When velocity is tripled the kinetic energy becomes 225 joules.
Kinetic energy is equal to one-half of the product of an object's mass and the square of its velocity. Velocity is change in displacement divided by time. If you have the kinetic energy and mass, you can calculate the velocity by taking the square root of the quotient of kinetic energy and mass, and thereby solving for the velocity.
Kinetic energy is given by the following equaiton: KE = 0.5*m*v^2 Where KE is kinetic energy, m is the object's mass, and v is its velocity. In other words, an object's kinetic energy is dependent on its mass and the square of its velocity. Note that since the velocity term is squared, velocity has a larger effect on kinetic energy than mass. For example, if you double mass, the kinetic energy will also double, but if you double velocity, kinetic energy increases by a factor of four.
KE=(1/2)mv246080 Joules
Kinetic energy is proportional to the square of the magnitude of velocity.
When you have kinetic energy, you must have a mass and a velocity since kinetic energy is half the product of the mass and the square of the velocity.
Time is not a factor, speed is velocity and velocity equates to kinetic energy. E=Mass * Velocity squared.
Kinetic Energy increases as velocity increases. Kinetic Energy = 1/2 * Mass * Velocity2
No. This is because velocity is not a mechanical energy.
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4
Multiply it by 4 (4 = 22)
Momentum is the product of mass and velocity. Kinetic Energy is the product of mass and velocity squared. As you can see, since Kinetic Energy is derived from mass and velocity, and Momentum is derived from mass and velocity, you cannot have one without the other.
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
