What does kinetic energy of a moving object depend on

The amount of translational kinetic energy from here on, the phrase kinetic energy will refer to translational kinetic energy that an object has depends upon two variables: the mass m of the object and the speed v of the object. The following equation is used to represent the kinetic energy KE of an object.

Answer: There are two factors that affect how much kinetic energy a moving object will have: mass and speed. The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity.

This means that an object with twice the mass and equal speed will have twice the kinetic energy while an object with equal mass and twice the speed will have quadruple the kinetic energy. Decreases in mass cause decreases in kinetic energy due to the aforementioned positive relationship between the two. In the case of a decrease in mass and velocity, kinetic energy must decrease because both of the determining factors decreased.

Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity. In SI units, mass is measured in kilograms, speed in metres per second, and the resulting kinetic energy is in joules.

As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy. Mentor: The kinetic energy does decrease as the ball rises in the air and slows. Then, when the ball comes down and increases in speed, the kinetic energy increases. According to the Law of Conservation of Energy, the amount of energy in a system must always remain constant.

Removing the kinetic energy can be accomplished by dissipating the energy to the atmosphere through friction or by converting it into another form of energy. The most common type of braking is a mechanical brake which inhibits motion through friction brake pads. In the case of a decrease in mass and velocity, kinetic energy must decrease because both of the determining factors decreased. The kinetic energy increases as the particles move faster. The potential energy increases as the particles move farther apart.

How are thermal energy and temperature related? When the temperature of an object increases, the average kinetic energy of its particles increases. The work-energy theorem states that the net work done by the forces on an object equals the change in its kinetic energy. Kinetic energy is the energy an object has because of its motion. The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.

Kinetic energy can be transferred between objects and transformed into other kinds of energy. A car moving 40 mph has four times as much kinetic energy as one moving 20 mph, while at 60 mph a car carries nine times as much kinetic energy as at 20 mph. Thus a modest increase in speed can cause a large increase in kinetic energy. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity. This means that an object with twice the mass and equal speed will have twice the kinetic energy while an object with equal mass and twice the speed will have quadruple the kinetic energy. The change in velocity means that there is a change in the kinetic energy of the object.

The change in kinetic energy of the object is equal to the work done by the net force acting on it. Work is the transfer of mechanical energy from one object to another. Since work is a movement of energy, it is measured in the same units as energy: joules J. As the ball falls towards the ground, its gravitational potential energy is transformed into kinetic energy. The kinetic energy of an object is the energy it possesses due to its motion.

When the ball collides, the kinetic energy is transformed into other forms of energy. Syedafatima Answered May 13, The mass and speed of and object is correct t or not. John Adney Answered Mar 23, Answer: it it the mass and speed of an object Why: beacause you need mass and speed to move an object or yourself Example: you use your muscles to move a cabinet.

While height is just one of the factors that dictates the safety of a fall along with falling surface and jump form it is something you should take into consideration while you plan your jump.

Falling from a height of 10 feet or more can result in serious, life-long injury or even death. Begin typing your search term above and press enter to search. Press ESC to cancel.
