What is the equation for a falling object?
The equation for the kinetic energy of a falling object is kinetic energy=1/2 an object's mass multiplied by it's speed squared. From this, we can work out the speed. First you need to know its weight and its kinetic energy. The kinetic energy is obtained by working out it's potential energy before it fell (Potential energy= mass multiplied by gravitational pull multiplied by height. Then, at whatever point during the fall, the decrease in potential energy marks the increase in kinetic energy. From then we work out the speed. Example; An object that weighs 8.1 kilograms is 10 metres above the ground. It's potential energy is therefore 8.1x10(gravitational pull on earth is always 10)x10. So it has a potential energy of 810 joules. it falls 5 metres, so it's potential energy is 8.1x10x5 (405 joules). The total energy, we know, is 810J, so 810-a05=405, giving it kinetic energy of 405J. The kinetic energy formula is then rearranged as speed squared=kinetic energy/ 0.5m. Our equation is therefore speed squared= 405/4.05, so speed squared=100. The square root of 100 is 10 so the speed is 10 metres per second (36 kilometres per hour).
If the same model plane travel 3 times faster than the same model airplane what is the kinetic energy of the faster plane?
The kinetic energy of an object varies as the square of its velocity (Kinetic energy = mv2/2). So a plane with the same mass travelling at 3 times the velocity will have 9 times the kinetic energy.
What is the length width and height of 3D object called?
The object's dimensions. Multiplied together they give the objects volume.
What are the 2 big categories that energy is divided into?
Two of the biggest areas of energy study in high school physics is kinetic energy (energy of an object that is moving) and potential energy (the potential of an object to do work - such as being being at the top of an inclined plane). However there are MANY other forms of energy.
What does independent variable and dependent variable mean and what they do?
It means that you can change one variable (the independent variable) freely, but that the other variable (the dependent variable) depends on the independent variable. For example, to calculate kinetic energy, the energy (for a given object) depends on the speed; if you change the speed, you change the kinetic energy. You can't change the kinetic energy directly, only indirectly by changing the speed.
What is kinetic enrgy?
Kinetic energy is the energy possessed by an object due to its motion. It is calculated as one-half the mass of the object multiplied by the square of its speed. The faster an object moves, the more kinetic energy it has.
What is energy of a moving object called?
The energy of a moving object is called kinetic energy. It depends on the mass and velocity of the object.
It refers to energy in motion?
That is called kinetic energy.That is called kinetic energy.That is called kinetic energy.That is called kinetic energy.
The energy of a moving object due to its motion is called?
Mechanical energy is the energy associated with the motion and position of an object. Thermal energy is the energy due to temperature.
What is energy of motion is called?
Energy of motion is called kinetic energy.
What is the kinetic energy called when it is moving?
Kinetic energy is when it's moving. Potential energy is when the object is motionless.
What is energy in motion called?
Energy in motion is called kinetic energy. It is the energy possessed by an object due to its motion.
If the velocity of an object is doubled its kinetic energy is multiplied by?
four times. Kinetic energy is directly proportional to the square of the velocity of an object, so if the velocity is doubled, the kinetic energy will be four times greater.
Is the energy that flows from a hot object to a cold object it is in contact with is called kinetic energy?
No, the energy that flows from a hot object to a cold object is called heat energy. Kinetic energy is the energy of motion of an object.
If the velocity of an object is tripled its kinetic energy is multiplied by?
When the velocity of an object is tripled, its kinetic energy is multiplied by 9. This is because kinetic energy is proportional to the square of the velocity (KE = 1/2 * m * v^2), so when the velocity is tripled, the kinetic energy is calculated as (3v)^2 = 9 * v^2.
When an object moves it uses kinetic energy which is called?
When an object moves, it uses kinetic energy.
Which is the best term to use when describing the energy of motion?
The energy that comes from an object's motion is called kinetic energy. The object's kinetic energy can be found by using the equation K=1/2mv2 which means that kinetic energy is equal to one-half of the object's mass multiplied by the square of its speed.
