Can an object move if there is no friction?

A: Motion is indeed possible without friction! Even if an object is stationary in one reference frame, in another reference frame moving with respect the first, that same object will be seen to be moving.

What happens to an object when there is no friction?

Friction stops things from sliding apart. If there was no friction everything would slide to the lowest point. It would be impossible to climb up anything. With no friction the only possible movement would be falling to a lower point under gravity.

Is it possible to move an object without accelerating it?

Yes, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity. For example, a puck sliding along a horizontal plane of ice after being hit with a hockey stick.

How do you know if the net force is balanced or unbalanced?

If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.

Is there a place with no friction?

Well there is no place where there is no friction. Every surface has some irrgularities,even if the surface is very smooth it will have micrscopic irregularities. Even in air and water the friction acts in the form of drag.

What is not possible without friction?

Without friction, you would not be able to walk, drive a car, or hold objects. Pens and pencils would not work. Although you normally hear about trying to reduce or eliminate friction, it actually has some important uses.

What might happen if there is no gravity and friction?

Humans and other objects will become weightless without gravity. If we have no gravity force, the atmosphere would disappear into space, the moon would collide with the earth, the earth would stop rotating, we would all feel weightless, the earth would collide with the sun, and as a consequence.

Can you have movement without force?

Yes, it is possible to have motion without a force being present. Newton’s first law states that, in fact, an object must continue to move at the same…

How do you know if a force is balanced?

When the forces on an object are equal and in opposite directions, the forces are balanced, and there is no change in motion.

What is balanced and unbalanced force with example?

When an object is in equilibrium, that is, it is not moving with changing speed, the net force acting on it is balanced. When an object is moving with changing speed, the net force on it is unbalanced. For example, when an apple falls from the tree an unbalanced force equal to its weight is acting on the apple.

How to estimate the strength of jointed rock masses?

Hoek and Brown (1980a, 1980b) proposed a method for obtaining estimates of the strength of jointed rock masses, based upon an assessment of the interlocking of rock blocks and the condition of the surfaces between these blocks.

Why do heavy objects fall to the ground at the same time?

In the absence of air friction both heavy and light objects will reach the ground at the same time. Galileo deduced this by devising clever experiments with balls rolling down inclined planes. Newton gave it his blessing by observing that a = F/M, i.e. the acceleration of an object is proportional to the force, F, on it divided by its mass, M.

How does friction affect the motion of an object?

Thus a force is required just to set the object in motion. Some of the peaks will be broken off, also requiring a force to maintain motion. Much of the friction is actually due to attractive forces between molecules making up the two objects, so that even perfectly smooth surfaces are not friction-free.

What is the relationship between the three types of rocks?

processes that explain the relationship between the three rock types: igneous, sedimentary, and metamorphic. Any rock type can become any other. rock formed from fragments of other rocks or the remains of plants or animals. the breaking down or dissolving of the Earth’s surface rocks and minerals.
