Because there is no net force acting on an object in equilibrium, then from Newton’s first law of motion, an object at rest will stay at rest, and an object in motion will stay in motion. Because the net force is equal to zero, the forces in Example 1 are acting in equilibrium.
Can an object ever be in equilibrium if the object is acted on by only?
No: equilibrium requires forces to be balanced, so it requires (at least) two forces, unless there are zero forces acting.
Can a body be at rest but not in equilibrium?
A body can be at rest in one type but not in equilibrium in another. , I taught physics. An object at rest in an inertial frame of reference is in equilibrium because the net force on the object is zero.
When a body is subjected to two forces and the body will be in equilibrium if the two forces are?
Detailed Solution. 1. Two force principle: If only two forces act on a body that is in equilibrium, then they must be equal in magnitude, co-linear and opposite in sense.
Can an object ever be in equilibrium if the object is acted on by aa single nonzero force?
If only a single nonzero force acts on an object, it will not be in mechanical equilibrium. There would have to be another or other forces to result in a zero net force for equilibrium.
Can a single force keep the particle in equilibrium?
Explanation: A body cannot be in the state of equilibrium if only a single force acts on it because we need two or more forces equal in magnitude but opposite in direction to cancel out each other.
Can a body be in equilibrium but not at rest if yes give example?
Answer: a pendulum at its extreme positions , an object at the highest point when thrown vertically upwards are examples of bodies at rest but not in equilibrium.
What type of motion does an object in equilibrium have?
A moving object is in equilibrium if it moves with a constant velocity; then its acceleration is zero. A zero acceleration is the fundamental characteristic of an object in equilibrium.
Is it possible for a body to be in equilibrium?
Dec 17, 2014. Yes! Such an equilibrium situation is called dynamic equilibrium . A body is said to be in equilibrium if the net force acting on the body is zero. By Newton’s second law, the acceleration of such objects will be zero. Zero acceleration implies a constant velocity. Constant velocity also includes zero velocity as a special case.
What is dynamic equilibrium in physics?
Such an equilibrium situation is called dynamic equilibrium . A body is said to be in equilibrium if the net force acting on the body is zero. By Newton’s second law, the acceleration of such objects will be zero. Zero acceleration implies a constant velocity.
What happens to an object moving at constant velocity in equilibrium?
An object moving at constant velocity could be in an equilibrium situation, and may have no forces acting on it or all the forces acting on it cancel, thereby having no effect. This is essentially one of newton’s laws a body in motion stays in motion unless acted upon by a net force.
What happens when the net force is zero in dynamic equilibrium?
Here the velocity is zero and remains unchanged. Dynamic Equilibrium : When the net force acting on an object is zero and if the object is moving at a constant non-zero velocity, then it is called dynamic equilibrium.
