The kinetic energy of a 50 newton object resting on the edge of a cliff 30 meters high is?

zero


The potential energy of a 50 newton object resting on the edge of a cliff 30 meters high is?

The word in your question that I keyed on is "resting". An object at rest has zero kinetic energy. If you meant potential energy, the answer is 1500 joules.


A 5kg object is being lifted to a height of 8 meters and is dropped what is the kinetic energy of the object at 2 m?

After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy. The potential energy (for the 6 meters) is mgh = (5 kg)(9.82 m/s2)(6 m) = 294.6 J, so that is also the kinetic energy, since potential energy has been converted to kinetic energy.After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy. The potential energy (for the 6 meters) is mgh = (5 kg)(9.82 m/s2)(6 m) = 294.6 J, so that is also the kinetic energy, since potential energy has been converted to kinetic energy.After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy.

What is the energy of a system by virtue of its motion?

That's called kinetic energy. The formula is: Kinetic energy = (1/2) x mass x velocity2. If mass is in kilograms, and velocity (or speed, really) in meters per second, the energy will be in Joules.


A rock weighing 98 newtons is pushed off the edge of a bride 50 meters above the ground what was the kinetic energy of the rock before it began to fall?

zero

What is the mathmetical formula for kinetic energy?

Kinetic Energy = 1/2(mass in kilograms)(meters per second)2


What is the kinetic energy of 9000kg railroad car before the collision?

The kinetic energy depends both on the mass and the speed. Convert the speed to meters/second, then use the formula: KE = (1/2)mv2 (kinetic energy = 1/2 x mass times velocity squared).

Is touching a kinetic energy?

Kinetic energy is the energy of motion. Your touching finger has mass and is moving some meters per second, so that motion is kenetic energy.


What are the factors in kinetic energy?

Kinetic energy = 1/2 x mass x velocity2. Mass in Kg, velocity in meters/sec, energy in Joules


What will be the kinetic energy and velocity of object of mass 62kg?

Its kinetic energy (in joules) will be (31) times (its velocity in meters per second)2 .


Is kinetic energy the same as static energy?

No, Potential Energy is the energy of an object that has the potential to move while kinetic energy is the energy of an object at motion. Potential energy is defined by Mass * Gravity(9.81ms-2) * height(In meters) Kinetic energy is defined by (1/2)*Mass*Velocity2


If you have a 2kg pendulum bob that is 6 meters above the ground at its high point and 1 meter at its low point how can you figure the kinetic energy?

Calculate the potential energy at its highest point. Don't use the 6 meters above the ground - use the 5 meter difference from the lowest point. This part of the potential energy gets converted into kinetic energy, when the pendulum is at its lowest point. Just assume that all the potential energy (for the 5 meters difference) get converted into kinetic energy.Calculate the potential energy at its highest point.
