## What is a 4 kg object moving across a frictionless surface with a constant velocity of?

According to Newton’s First Law of Motion, the 4 kg object continues its uniform motion along the frictionless surface as a straight line with a constant velocity of 2 m/s, until an unbalanced external force is acting on it.

## What force is required to keep an object moving with a constant velocity of 2 m s along a frictionless surface?

Since the object is moving on a frictionless table, no force is required to keep the object moving with the same velocity. Q. An object of mass 10 kg is sliding with a constant velocity of 2 m/s on a frictionless horizontal table.

## When an object is moving on a frictionless surface?

Once the force is removed, since there is no friction, what remains in motion stays in motion at constant velocity. If object is moving in a friction less surface with a constant velocity, Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero.

## How much force is required to keep a body moving with constant speed on a frictionless surface?

There is no external force required in case of constant velocity, where frictional forces are zero.

## What happens to velocity on a frictionless surface?

Galileo concluded that an object moving on a frictionless horizontal surface should move with constant velocity.

## What is an object of mass 10 kg is sliding on a frictionless horizontal surface?

The correct answer is 0 newtons.

## How to keep a particle moving with a constant velocity on a frictionless horizontal surface and external force?

Expert-Verified Answer To keep the particle moving, moving with constant velocity on a frictionless horizontal surface an external force need not to apply continuously. As the horizontal surface is frictionless so there will be not any frictional force on the body in the opposite direction of its motion.

## What is the first law of friction?

First law of friction: The amount of friction is proportional to the normal force exerted between the surfaces. Second law of friction: Friction does not depend on the area of contact between the object and the surface. Third law of friction: Friction force also depends on the nature of the surfaces in contact.

## What net force is required to keep a 5kg object moving with a constant velocity of 10m s?

Answer: Net force is always m•a. In this case, the velocity is constant so the acceleration is zero and the net force is zero. Constant velocity motion can always be associated with a zero net force.

## Which object is frictionless?

Frictionless planes do not exist in the real world. However, if they did, one can be almost certain that objects on them would behave exactly as Galileo predicts. Despite their nonexistence, they have considerable value in the design of engines, motors, roadways, and even tow-truck beds, to name a few examples.

## What does frictionless mean in physics?

adjective. /ˈfrɪkʃnləs/ /ˈfrɪkʃnləs/ ​with no resistance between a surface or substance and something that is moving along or through it.

## Why is frictionless surface impossible?

A frictionless surface is not possible is not possible because the surface cannot have a zero friction surface. According to Newton if a body is in motion it will continue to be in motion, if a body is at rest, it will be in rest until external force is applied to it. Friction is the cause behind this law.

## What is an object that moves with a constant velocity?

Motion with Constant Velocity: When an object is moving with constant velocity, it does not change direction nor speed and therefore is represented as a straight line when graphed as distance over time. You can also obtain an object’s velocity if you know its trace over time.

## What is a mass of 10kg moves with a velocity of 4m?

An object of mass 10 kg is moving with a uniform velocity of 4 ms-1. The kinetic energy possessed by the object is 80 J.

## What is the constant velocity of an object that is reached when the drag force equals the force of gravity?

The terminal velocity would be the same if an object was dropped from twice the height (as long as gravity and air resistance remain the same at either height). Terminal velocity is reached when the force from air drag equals the force of gravity.

## What is the of an object moving with constant velocity?

Since the object is moving with a constant velocity, it means an acceleration of the body will be zero.
