When an object is not moving the forces applied to it are balanced.
It can be said that the net force applied on the object is zero or that the object is in translational equilibrium. Keep in mind that these terms can also be applied if the object is moving at a constant velocity.
If an object is not moving OR if it is moving at constant velocity (i.e., it is not ACCELERATING):* The vector sum of the forces on the object is zero. * Also, the forces are said to be in balance.
Yes, if the forces are equal and acting in opposite directions, the net force will equal zero and that object can be said to be at rest.
If an object is not moving or if it is moving with a constant velocity (meaning there is no acceleration), the sum of the forces acting on it is equal to zero. A stationary object is said to be in static translational equilibrium, while an object with a constant velocity is said to be in dynamic translational equilibrium. Typically, an object at rest on the ground has two forces acting on it: Gravity and the Normal force of the ground. Normal force counters gravity and prevents things from falling through the ground.
The forces are said to be static.
When an object is not moving, it is said to be stationary.
unbalanced or balanced forces
If the sum of all forces acting on one object is not exactly zero, the forces are said to be unbalanced. In that case, the object will accelerate.
It means -- the vector sum of all individual forces on it is zero; -- the effect of all the forces is the same as if there were no forces acting on it; -- the forces on the object are said to be 'balanced'. Examples: -- 30 tough guys pulling on one end of a rope, 30 other tough guys pulling in the opposite direction on the other end of the rope, and the rope going nowhere; -- two little girls pulling hard on the same doll, and the doll not moving; -- two strong shoppers pulling hard in opposite directions on the same shopping cart, and not moving it.
If the sum of all forces acting on an object is not zero, the forces are said to be unbalanced. In that case, the object will accelerate in accordance with Newton's Second Law.
In that case, the forces are said to be unbalanced.
No, it can be moving. A body is said to be in equilibrium when the forces acting on it cancel each other out, that is, the body is not accelerating. Therefore an object might be moving at a constant speed and be considered in equilibrium.
balanced --> the forces cancel each other. =================================
If two or more forces acting on an object don't add up to zero (i.e., when doing a vector addition), the forces are said to be UNBALANCED, and the object will accelerate.
If the vector sum of forces on an object is zero, the forces are said to be balanced. Otherwise they are said to be unbalanced. Unbalanced forces will cause an acceleration, according to Newton's Second Law (a = F/m, where F is the net force, that is, the vector sum of all forces acting on the object).
Forces that cancel each other out are said to be balanced.
The Law of Inertia (Newton's First Law) implies that an object in motion will remain in motion unless a force is applied to stop it. That being said, most objects will naturally decelerate due to gravity or air resistance. Objects can only move forever in a perfect vacuum.
An object experiencing balanced forces is said to be in equilibrium. Thus, unless an outside force acts upon the object, it will remain either stationary or at constant speed, it will not accelerate.
No. All objects tend to adhere to their current speed (magnitude and direction), it will only change when a force is being applied on said object.
Galileo came up with the idea of inertia. Not taking Aristotle's view that an object must have a force acting on it to keep moving, Galileo said that an object would move continuously in a straight line as long as no outside forces acted on it.
Differ... from what?Forces (acting on an object) are said to be BALANCED if the sum (i.e., the vector sum) of all such forces are equal to zero; UNBALANCED otherwise. Such an unbalanced force will result in an acceleration of the object.
The answer to the question seems to be clearly given within the question. You have said that the object " ... is moving ... " in a straight line. Therefore we conclude that if you have been honest with us, then the object is certainly in motion.
They are said to be in equilibrium.
No. Impulse is a change in momentum and so a moving object with a constant velocity has no impulse. in real life air resistance imparts an impulse to the object slowing it down but the object cannot really be said to have impulse
