A 10 kg rock is pushed off the edge of a bridge 50 meters above the ground. what was the kinetic energy of rock befor it began to fall?
zero
A 10 kg rock is pushed off the edge of a bridge 50 meters above the ground. What was the kinetic energy of the rock at the midway point of its fall?
2450
What is the kinetic energy of a bicyclewith mass 10 kg traveling at a velocity of 3ms?
The kinetic energy of the bicycle can be calculated using the formula: KE = 0.5 * mass * velocity^2. Plugging in the values: KE = 0.5 * 10 kg * (3 m/s)^2 = 45 Joules. So, the kinetic energy of the bicycle is 45 Joules.
When an object falls which energy changes to?
As the object falls, it PEG or potential gravitational energy becomes kinetic energy. Before falling, it has for example 10 joules of PEG and 0 joules of Kinetic energy. As it falls, the PEG decreases and the kinetic energy increases, until it hits the ground, when all the energy is dispersed as sound, heat, etc.
What are 10 objects with kinetic energy?
Moving car Falling apple Swinging pendulum Rolling ball Flying airplane Flowing river Rotating wind turbine Spinning top Jumping athlete Bouncing basketball

zero
What will be the kinetic energy of the ram of a pile driver when it suddenly undergoes a 10-kJ decrease in potential energy?
10-kj will be added to the Kinetic Energy. Remember the law of conservation of energy. E=PE+KE. and Efinal = Einitial.

Do changes in velocity and mass have the same effect on kinetic energy?
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.
If 100J of energy are required to draw a bow what is the kinetic energy of the arrow at the moment of release?
At the moment of release, all the energy stored in the bow (100J) is converted to the kinetic energy of the arrow. So, the kinetic energy of the arrow at that moment is 100J.

Bicycle going 10 ms on a flat road demonstrates energy?
The answer is kinetic.
How much work must be done on a 10-kg bicycle to increase its speed from 5 ms to 10 ms?
3000 J
What is The Rotational Kinetic Energy of the Earth?
The rotational kinetic energy of the Earth is approximately 2.14 × 10^29 joules. This energy is a result of the Earth's rotation about its axis. It contributes to the overall energy balance of the Earth system.
Two things moving at 10 km Which one has more kinetic energy?
The object with more mass will have more kinetic energy, assuming they are both moving at the same speed. Kinetic energy is directly proportional to an object's mass and velocity, so the object with greater mass will have a greater kinetic energy.
When an object falls which energy changes to?
As the object falls, it PEG or potential gravitational energy becomes kinetic energy. Before falling, it has for example 10 joules of PEG and 0 joules of Kinetic energy. As it falls, the PEG decreases and the kinetic energy increases, until it hits the ground, when all the energy is dispersed as sound, heat, etc.
