Is it necessary to have a nonzero net force when an object is moving?
Newton’s first law states that an object at rest tends to remain at rest, and an object in motion tends to remain in motion with a constant velocity (constant speed and direction of motion), unless it is acted on by a nonzero net force.
When a nonzero net force acts on an object?
An object’s velocity (a vector) does not change if and only if the net force acting on the object is zero. In other words, if there is no net force on an object, its speed and direction of motion do not change (including if it is at rest).
Does a body necessarily move in the direction of the net force acting on it?
While the net force may not be in the same direction which the object is moving, it is always in the direction that the object is accelerating. So if the acceleration is centripetal, then so is the net force. For circular motion, what is the direction of the net force vector?
Is it possible for an object to move if no net force is acting on it explain?
Is it possible for an object to be in motion if no net force is acting on it? Explain. yes it is possible because when the net force is zero and acceleration is zero. so if the object has some constant velocity it continues with the same velocity until it has some external acceleration.
What are forces that produce a nonzero net force?
*Motion, Forces, & Energy – Ch. 2 “Forces” Games
| A | B |
|---|---|
| unbalanced forces | Forces that produce a nonzero net force, which changes an object’s motion. |
| balanced forces | Equal forces actring on an object in opposite directions. |
| friction | The force that one surface exerts on another when the two surfaces rub against each other. |
How will an object move if it is acted on by a nonzero net torque and a net force of zero?
If net torque is zero, the object will be moving at constant velocity or remain static If net torque is zero, the angular momentum is conserved If net force is zero, the object will be rotate at constant angle velocity or not rotate at all.
Can an object have a net force equal to zero if only a single nonzero force acts on it?
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.
Which statement describes the motion of an object when the net force is zero?( 1 point?
If an object experiences no net force, its velocity will remain constant. The object is either at rest and the velocity is zero or it moves in a straight line with a constant speed.
What is no net force?
No net force means that the acceleration is zero based on Newton’s second law. This is the case of uniform linear motion, which is characterized by constant velocity and zero acceleration. Examples include an object falling in a fluid when it has reached its terminal velocity and a car traveling at constant velocity.
What would be the net force on an object if the object’s acceleration is 0?
If there is zero acceleration, that means there is no net force on the object, or .
Under what condition a net non zero force acts on an object and yet does no work on the object?
Newton’s First Law is the law of inertia. An object with no net forces acting on it which is initially at rest will remain at rest. If it is moving, it will continue to move in a straight line with constant velocity.
