What else can I help you with?
Explain how you can determine the direction of a force by watching an object's change in motion?
If you are pushing an object across the floor, the object will move in the direction you push it. If you took yourself out of the picture and watched the box moved as if you weren't there you could see the direction the object was being pushed. You could utilize all different methods like a graph, reference points, or vectors but if you understand it in simple terms these methods are just names for the way we would instinctly try to figure it out.
What happens if the sum of all the forces acting on a moving object is zero?
If the sum of all the forces acting on a moving object is zero, the object will continue to move at a constant velocity in the same direction. This is described by Newton's First Law of Motion, which states that an object will remain in its state of motion unless acted upon by an external force.
Can an object have a non zero force and have constant kinetic energy?
an object can have a non zero force acting upon it if and only if the sum of all of the forces on the object is still equal to zero. The sum of the forces is equal to mass times acceleration. If an object is accelerating, then it does not have a constant KE therefore the sum of the forces must be equal to 0 so that acceleration is also equal to zero. For instance, take the case of an object falling through the air. Initially, the force of gravity is accelerating the object downward and it is gaining KE. After some time, this object will reach terminal velocity. At this point, the resistance force of the air on the object negates the force of gravity and the sum of the forces is equal to zero. The object now falls at a constant velocity and in turn also a constant KE. It is still being acted upon by the force of gravity and the resistance force but these forces are canceling each other out. =============================== I don't like to delete an answer that somebody put a lot of effort into, and supervisors don't like it when I become plainly uncomplimentary. So all I can say is: Use the above answer at your own extreme peril, and far better to ignore it. Especially the 1st and 3rd sentences.
If an odject is at rest all forces acting on that obkect is?
If an object is at rest 2 forces are still acting on it (if done on a planet) gravity pushing the object down. And the up force which is the force exerted by ground upwards against the object. Gravity being the greater force keeps the object on the ground, but the upforce prevents the object from basically ploughing through the ground.
What is determined by combining forces?
When combining forces, the resulting force is determined by adding up the individual forces vectorially. This means considering the direction and magnitude of each force to determine the overall effect on an object's motion or equilibrium. The combined force may result in an object accelerating, decelerating, changing direction, or remaining at rest, depending on the net force.
What is zero accelaration?
When an object is not accelerating at all. It has constant velocity.
If an object in not accelerating what can you determine about the sum of all the forces on the object?
If an object is not accelerating, it means that the sum of all forces acting on the object is equal to zero. This is in accordance with Newton's first law of motion, which states that an object will remain at rest or in constant motion unless acted upon by an external force.
If an object is not accelerating it can exist in what 2 other states of motion?
If an object is not accelerating, it can exist in two other states of motion: constant velocity motion (moving with a steady speed in a straight line) or at rest (not moving at all).
What does the term balance mean?
If you add up all the forces acting on an object, they are balanced if they equal zero. (They cancel each other out). If the forces acting on a object are balanced, then the acceleration of that object is zero. It may still be moving, but it is not accelerating. An object that is not accelerating, (the sum of the forces acting on it is zero), is in equilibrium.
How do you find the displacement of an object accelerating from rest?
If the motion is all in a straight line, then Displacement = (1/2) x (acceleration) x (time spent accelerating)2
How can you tell visually if the forces on an object are balanced?
If the object is not moving, or is traveling at a constant velocity, all forces acting on the object are equal and opposite to each other. If the object is accelerating (speeding up, slowing down, or changing direction) the forces are not balanced.
What condition does a moving object be in equilibrium?
A moving object can be in equilibrium if the vector sum of all the forces acting on it is zero. This means that the object is not accelerating in any direction, and its velocity remains constant.
The overall force on an object after all the force are added together is called the?
accelerating force
How can you tell if the force on an object are balanced?
If the object is not moving, or is traveling at a constant velocity, all forces acting on the object are equal and opposite to each other. If the object is accelerating (speeding up, slowing down, or changing direction) the forces are not balanced.
Is something accelerating with a constant speed?
That is possible, for example, if an object moves around in a circle. In this case, the velocity changes all the time; the speed does not.
Is it true that on a level surface applied forces equals weight?
No, on a level surface, the sum of all applied forces equals zero if the object is not accelerating. Weight is the force exerted by gravity on an object and is equal to the mass of the object multiplied by the acceleration due to gravity.
