## What is the work done on a frictionless horizontal surface?

The work done against the gravity when a body is move horizontally along a frictionless surface is zero as the force of gravity acts perpendicular to the direction of motion.

## Can two objects on a horizontal frictionless surface have a collision in which all the initial kinetic energy of the system is lost?

Yes, if both collide head on with a momentum of equal magnitude in completely inelastic collision, then both would be at rest after the collision, resulting in initial KE being lost.

## When an object rests on a horizontal frictionless surface?

An object rest on a horizontal fricitionless surface. A horizontal force of magnitude F is applied. This force produces an acceleration always as there is no friction.

## Is there work on a frictionless surface?

Yes, but it is the net work done on the body that equals zero, not the work you did on the body. The net work equals the positive work of Fd that you did, plus the negative work done by the opposing force that resulted in bringing the body to rest at d.

## Should an object moving on a frictionless horizontal surface move with constant velocity?

Newtons law of motion states that a body moving with constant velocity will continue moving with same velocity if any external force is absent. In the given case above case surface is frictionless and any other external force is absemt so body will move with same constant velocity.

## What are the 2 types of collision?

• Inelastic collisions: momentum is conserved,
• Elastic collisions: momentum is conserved and kinetic energy is conserved.

## What is the formula for kinetic energy before a collision?

Kinetic Energy and the Inelastic Collision Formula Since KE is 1 2 m v 2 , the total kinetic energy before the collision is K E i = 1 2 ( m 1 v 1 2 + m 2 v 2 2 ) , while the total kinetic energy after a perfectly inelastic collision is K E f = 1 2 ( m 1 + m 2 ) v ′ 2 .

## Can we jump of a frictionless horizontal surface?

A human could only jump straight up on a smooth surface with no friction. Because there is no friction to push against him and keep him from sliding over, any force applied parallel to the surface will cause the person to slip. When all they can do is move up and down, no one will be able to move sideways.

## What is frictionless surface in physics?

In physics, a frictionless surface refers to an ideal surface that does not experience any type of friction.

## Is there acceleration on a frictionless surface?

Explanation: If no forces are acting upon the skater and he is on a frictionless surface, then that means he has no net acceleration. Presumably the skier has mass, therefore the acceleration must be zero.

## What is the work done on horizontal surface?

When a body moves in a horizontal plane, a uniform velocity should be maintained also a uniform force must be applied. The applied force acts along the direction of motion of the body, so the work done will be positive.
