Why is it easier to move an object when it is already in motion?

It is easy to move an object already in motion than when it is at rest…. because of friction the object sticks to its surface… This energy is in addition to the energy that it takes to accelerate the object….. A moving object has already overcome this additional energy…

Why is it easier to move an object already in motion than to get it started for Class 8?

Answer: When the box starts sliding, the contact points on its surface, do not get enough time to lock into the contact points on the floor. So, the sliding friction is slightly smaller than the static friction. Hence, it is somewhat easier to move the box already in motion than to get it started.

Why is it harder to set an object in motion than to keep it moving?

Static friction is subtle because the static friction force is variable and depends on the external forces acting on an object. It is harder to move a stationary object than it is to keep a moving object in motion.

What is required to move an object that is in motion?

An object at rest stays at rest and an object in motion stays in motion at a constant speed and direction unless acted upon by an unbalanced force. It stated that if an object is moving, some sort of force is required to keep it moving.

Why is it easier to move a box which is already moving than the one which is at rest?

Answer: It is easier to move a box which is already in motion then to move it from rest because when th box is in motion its net speed working on it is more ,so it is easier to move a box which is already in motion . Static friction is little more than sliding friction for any given pair of surfaces.

Which objects was harder to move Why?

Heavy objects are harder to move than light ones because they have more inertia. Inertia also makes it harder to stop heavy things once they are moving.

Why is it easier to keep sliding an object once it has been put in motion than to make it slide from rest?

The sliding friction is smaller than the static force. Since the sliding friction is smaller than the static friction it is easier to keep an object moving which is already in motion than to move the same object from rest.

Why is it easier to move the box?

Why is it easier to move smaller objects than bigger objects?

The amount of force needed to move an object is related to the object’s mass. 2. The greater the object’s mass, the greater the force needed to move it, stop it or change its speed or direction. An object with a small mass is easier to stop or cause a change in motion than an object with a large mass.
