If something is moving, no force is required for that something to continue moving. That doesn't mean there are no forces acting on Earth; for example, the Sun attracts Earth towards it. But that's not what keeps the Earth moving.
A particle in motion without any external force acting on it will continue moving at a constant velocity in a straight line, following Newton's first law of motion. This motion will remain unchanged unless an external force is applied to alter its velocity or direction.
force! (i think) It was in my science book... so that is what i am assuming!It is actually an unbalanced force not just a force. -Kelsey Munroe
If the frictional force is eliminated, the body will continue to move at a constant velocity in the absence of any other external forces acting on it. This is based on Newton's first law of motion, which states that an object in motion will stay in motion unless acted upon by an external force.
This statement is not accurate. In the absence of any external forces, an object in motion will continue to move at a constant velocity due to Newton's First Law of Motion. Opposition to motion arises when there is a force acting on the object that opposes its direction of motion.
I think you mean 10 letters: unbalanced force.
The primary factor that can change the motion of an object is an external force acting on the object. This force can cause the object to accelerate, decelerate, change direction, or stop its motion completely.
The centripetal force acting on a satellite in uniform circular motion around Earth is directed towards the center of Earth. This force is necessary to keep the satellite moving in a circular path instead of following a straight line.
If there are no external forces acting on a system, it will remain in its current state of motion or rest. This is described by Newton's first law of motion, which states that an object will continue in its state of rest or uniform motion in a straight line unless acted upon by an external force.
To make a body move from rest, external force is necessary. Once it starts moving, it will continue to do so until external forces act on it. So for an object to be in motion no force is required.
The two external forces are friction and air resistance. Friction is the force opposing motion when two surfaces are in contact, while air resistance is the force acting in the opposite direction to an object's motion as it moves through the air.
The three forces that can cause an object to change its motion are gravity, friction, and applied force. Gravity pulls objects towards the center of the Earth, friction opposes motion by acting in the opposite direction, and applied force is any external force being exerted on the object.
An object's motion can't change unless an external force is acting upon it. This is Newton's First Law of Motion.
