If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. The word “kinetic” comes from the Greek word “kinesis” which means motion. Kinetic energy can be passed from one object to another in the form of a collision.

When is kinetic energy transferred from object to object. In a generator, kinetic energy is transferred into. There is a finite amount of energy in the universe.

When an object is falling, all its potential energy converts into kinetic energy. As soon as the object hits the ground, its kinetic energy is converted into various other forms of energy such as sound, heat, potential energy etc. The KINETIC ENERGY gets CONVERTED into Heat and Sound energy on hitting the ground.

Radiation is the transfer of thermal energy from one object to another by electromagnetic waves. Conduction is the transfer of heat energy that occurs between two objects that are touching. During conduction, heat will always transfer from the hotter to the colder object.

What are the different ways that energy can be transferred?

• Conduction: Heat is thermal energy, and in solids it can be transferred by conduction. Heat is passed along from the hotter end of an object to the cold end by the particles in the solid vibrating.
• Convection: Fluids, that is both gases and liquids, can transfer heat energy by convection.
• Radiation:

Heat can be transferred in three ways: by conduction, by convection, and by radiation.

• Conduction is the transfer of energy from one molecule to another by direct contact.
• Convection is the movement of heat by a fluid such as water or air.
• Radiation is the transfer of heat by electromagnetic waves.

Energy can be transferred mechanically through the movement of the parts in machines, and when the motion or position of an object changes. Sound waves and seismic waves (formed during earthquakes) are mechanical waves that transfer energy through materials and from place to place.

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

The amount of electrical energy transferred to an appliance depends on its power, and on the length of time it is switched on for. The kilowatt hour (kWh) is used as a unit of energy for calculating electricity bills.

The amount of energy transferred from the power source to the appliance will depend on two things, the power rating of the appliance, eg the buzzer, and the length of time it is on. Then we simply multiply these two numbers together to get a value for the amount of energy transferred.

Candidates should understand that when an object is raised vertically work is done against gravitational force and the object gains gravitational potential energy.

When an object is lifted, work is done. When work is done in raising the height of an object, energy is transferred as a gain in the gravitational potential energy of the object. For example, suppose you lift a suitcase of mass through a height . The weight of the suit case is a downward force of size .

Brainly User. energy of an object that has been lifted is kinetic energy when it was in motion.

Potential energy is energy that is stored in a person or object. Gravitational potential energy is due to the position of an object above Earth’s surface. Gravitational potential energy depends on an object’s weight and its height above the ground (GPE = weight x height).

ENERGY CAN NEVER BE CREATED NOR BE DESTROYED. When we lift any object above the ground, it gains potential energy as it is now at a particular height with respect to the ground (which is the datum here). Now one may ask that from where this energy came?

Here are some Kinetic Energy Examples:

• when you are walking or running your body is exhibiting kinetic energy.
• A bicycle or skateboard in motion possesses kinetic energy.
• Running water has kinetic energy and it is used to run water mills.

You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy. When the rubber band is released, the potential energy is quickly converted to kinetic (motion) energy.

Potential energy is converted to kinetic energy, which is the energy exerted by a moving object. An active pendulum has the most kinetic energy at the lowest point of its swing when the weight is moving fastest.

What Factors Affect Kinetic Energy? The two main factors that affect kinetic energy are mass and speed. Why? Because the motion of an object depends on how fast it’s traveling, but also how much mass it has, though velocity is the more important factor.

The rubber band has a mass of 1.09 grams. This puts the specific energy at 1651 J/kg for stretching and 6605 J/kg for twisting.

The energy that was gained by the spring is called elastic potential energy. The amount of elastic potential energy stored in the spring is equal to the amount of work done or energy applied to stretch the spring.

A simple way to understand this formula is Y=stressstrain. The stress is the amount of force applied to the object, per unit area (F/A). The strain is the relative change in the length of the solid (ΔL/L0).

Rubber elasticity refers to a property of crosslinked rubber: it can be stretched by up to a factor of 10 from its original length and, when released, returns very nearly to its original length. This can be repeated many times with no apparent degradation to the rubber.
