What else can I help you with?
What happen to the potential energy of an object as it falls?
As an object falls, its potential energy decreases and is transformed into kinetic energy. This is due to the force of gravity doing work on the object as it moves downwards. The potential energy is converted into kinetic energy, which increases the object's speed as it falls.
When you increase the height of a ramp which increases the angle does the efficiency for kinetic energy increase of decrease?
When you increase the height of a ramp, the efficiency for kinetic energy decreases because you are doing work against gravity to lift the object higher. This means less of the initial potential energy is converted into kinetic energy compared to when the ramp is lower.
What type of energy is used by objects doing work?
kinetic energy
What happened to the friction force as the weight or the pulled objects increased?
As the weight of the pulled object increases, the friction force also increases. This is because there is more contact between the surfaces, leading to greater resistance. The friction force is directly proportional to the normal force acting on the object, which increases with weight.
How does kinetic energy and potential energy switch?
work=change in kinetic energy, doing work on an object by moving it up increases that object's potential energy because it has the POTENTIAL to fall due to gravity. kinetic energy is lost in the movement of the object. However, throughout an entire closed system, the total energy in joules (or kinetic enery plus potential energy) does remain constant. this is useful because the initial energy and the final energy most be equal, and if thats true, then initial kinetic energy plus initial potential energy must equal final kinetic energy plus final potential energy. does that help?
Which of the following has kinetic energy?
An object in motion, such as a moving car or a swinging pendulum, has kinetic energy. It is the energy an object possesses due to its motion.
What force Force that allows objects to keep on doing what they are already doing?
The force that allows objects to keep on doing what they are already doing is called inertia. Inertia is the tendency of an object to resist changes in its state of motion.
If the acceleration of an object is constant what is the object doing?
With poor language we cannot assess. Any way the objects speed goes on increasing
What is the relationship between kinetic energy and work?
Relationship between work and kinetic energy. Work is defined as the result of a force moving an object a distance and is stated by the equation W=Fd. But the result of the force being applied on the object also means that the object is moving with some given velocity, according to the equation for force as F=ma. From those two equations, it can be shown that work is equivalent to kinetic energy Kinetic Energy =1/2mv2
What are all objects in space constantly doing?
Objects in space are always Floating and/or orbiting a larger object because of the lack of gravity in space.
In physics the desire of an object to keep doing what it is doing is termed .?
The desire of an object to keep doing what it is doing is called inertia. "What it is doing" means that it is in motion or at rest,
In physicsdesire of an object to keep doing what it is doing is termed?
Inertia, but you really shouldn't call it a "desire." Inertia is a property of matter, not a desire.
