What is inertia and orbital motion?
The natural tendency of an object to not move (if it wasn't moving), or to keep moving (if it was moving). Inertia is the characteristic that a object will want to stay at rest or in motion. You can feel this in a buss when it suddenly moves this is why you get sent backwards.
How can you tell if a force is balanced or unbalanced by looking at it?
2 Forces are unbalanced when an object that is not moving starts moving or changes speed or direction. Balanced forces are the opposite they are where an object that is not moving stays still or an object that is moving stays at a constant pace.
What are the archemedes principle?
The bouyant force on an object is equal to the weight of the fluid the object displaces.
The force required to slide an object is equal to?
The force required to accelerate an object depends on the object's mass. Newton's second law states that Force = Mass * Acceleration. Re-written to solve for acceleration, this becomes Acceleration = Force/Mass. Basically, this means that the more mass an object has, the more force is required to accelerate it. Also, the faster you want to accelerate the object, the more force you will need.
Does a force always cause things to move?
You need to look at the net force... which is the resultant of all the forces... if there is a net force then there will be an acceleration and therefore the object will move.. however there can be many forces acting on a single object but as long as those are in equilibrium then the object will not move... so to answer your question: a force does not always cause things to move... also.. a thing can be moving without a force... see newtons first law..
How do you calculate the normal force with friction in a given scenario?
To calculate the normal force with friction in a scenario, you need to consider the weight of the object and the frictional force acting on it. The normal force is equal to the weight of the object in the absence of any other forces. When friction is present, you need to account for the frictional force opposing the motion. The normal force can be calculated using the equation: Normal force Weight of the object - Frictional force.
What is non frictional force?
Non-frictional force refers to forces that act on an object without involving any friction between surfaces. Examples include gravitational force, electromagnetic force, and normal force. These forces can cause motion, deformation, or other effects on an object without the need for friction between surfaces.
Why do you need small force to maintain a heavy object in motion?
Inertia is the resistance to change of an object in motion. In other words, an object at rest wants to stay at rest, and an object in motion wants to stay in motion. this is why it might take a person's whole body strength to start pushing a car down the road from a dead stop, but once it is in motion, it may only take one hand to keep it moving. Once you stop pushing the car, it slows and eventually stops because the frictional forces acting against the car's motion are greater than those keeping it moving.
What is needed to change an object's state of motion?
With changing the "state of motion", I assume you want to change the velocity. What you need here is a force, applied on the object. The amount of acceleration is given by Newton's Second Law.
What is the force that keeps an object in motion?
An object which is moving doesn't need a force to keep it moving.
To start or change the motion of an object do you need unbalanced force or balanced force?
Doesn't matter Balanced Force would mean the object is traveling at a constant velocity due to Newton's First Law of Motion (Law of Inertia) Unbalenced Force would mean the object is accelerating (or decellerating) due to Newton's Second Law of Motion
What is needed to change the speed of an object?
To change the speed of an object, you need to apply a force to it. The magnitude of the force and the direction in which it is applied will determine how the speed changes. If the force is in the same direction as the motion, the object will accelerate; if the force opposes the motion, the object will decelerate.
Why no force is needed to maintain motion?
According to Newton's first law of motion, an object in motion will remain in motion unless acted upon by an external force. This means that if no external force is applied to an object, its motion will not change. So, if an object is already moving, it will continue to move at a constant velocity without the need for a force to maintain that motion.
What is required to set an object in motion?
To set an object in motion, you need to apply a force to overcome any inertia the object may have. This force can come from pushing, pulling, or applying energy to the object in some form. Once the force is applied, the object will begin to move in the direction of the force.
What foce needs to overcome to move something?
To move an object, you need to overcome the force of static friction, which is the resistance encountered when trying to move an object at rest. Once the object is in motion, you need to continue overcoming the force of kinetic friction, which is the resistance encountered while the object is in motion.
What fraction of the mass is needed to halt the object's motion?
To halt an object's motion, you need to apply a force equal to the object's mass multiplied by its acceleration. This means that the fraction of the object's mass needed to halt its motion is 1.
What two things need to happen for there to be work done on an object?
If he object moves as a force is applied and the direction of the objects motion is the same as the direction of the same force.
