What else can I help you with?
Does centripetal force do work on the particle on which it acts?
No, because the force is perpendicular to the movement.
Why magnetic force not do any work?
Magnetic force does not do any work because it acts perpendicular to the direction of motion of the charged particle. Work is defined as force acting in the direction of motion, and since magnetic force acts perpendicular to the motion, it does not transfer energy to the particle in the form of work.
What is the energy of an object or particle has because of its location relative to another object or particle?
The energy of an object or particle due to its location relative to another object or particle is called gravitational potential energy. This energy is determined by the mass of the objects, the distance between them, and the gravitational constant. It represents the potential for work to be done as a result of the gravitational force between the objects.
What can be said about the speed of a particle if the net work done on it is zero?
In that case, basically no force acts on the particle, and the particle moves at a constant speed. This constant speed may, or may not, be zero.
Why no work is done by the force acting on Venus as it moves?
No work is done by the gravitational force acting on Venus as it moves in its orbit because the force is always perpendicular to its direction of motion. Work is defined as the product of force and displacement in the direction of the force; since the gravitational force acts towards the Sun while Venus moves along a curved path, the angle between the force and the displacement is 90 degrees, resulting in zero work done.
What force of attraction acts between all objects?
Gravity is a force that attracts physical bodies to each other. Galileo Galilei was the catalyst for modern work on gravitational theory.
When a ball rises vertically to a height h and returns to its original point of projection the work done by the gravitational force is?
The work done would be calculated by 2mgh. The force on the ball is calculated by mg, and work done is by Fd, where d is 2h (the force acts on both upwards height and downwards height, thus twice the distance).
How can the work-kinetic energy theorem explain why the force of sliding friction reduces the kinetic energy of a particle?
Work = change in Kinetic Energy Because friction acts in the opposite direction of the motion of an object, kinetic energy must be decreased in order to maintain the above equation. Friction opposes motion. Friction converts the kinetic energy of a particle into heat and sound.
A net external force acts on a particle this net force is not equal to zerois this sufficient information to conclude that the kinetic energy of the particle change?
No. Example: A planet in a circular orbit around a star. The net external force acting on the planet is the mutual force of gravitation between the planet and the star. The planet's speed is constant, so its Kinetic Energy = 1/2 m V2 is constant. The net external force causes a continuous change in the planet's velocity vector, although the magnituide of the vector is constant, and that's the only thing the K.E. depends on.
Which force do not work on the body on which it acts?
frictional force
When a particle is moving in a circular motion what is the work done by it?
When a particle is moving in a circular motion at a constant speed, the work done by the particle is zero. This is because work is defined as force applied over a distance in the direction of the force, and in circular motion, the force and displacement are perpendicular to each other, resulting in no work being done.
What is the size of the force multiplied by the distance through which the force acts?
Work W. The dot product of Force and Distance through which the force acts is called Work . W=F.d
