Can the sum of the torques on an object be zero while the net force on the object is nonzero?
Yes. Consider an object with no torques acting on it (therefore the sum of the torques is obviously zero) but with a force directed through its center of mass.
How about a freely spinning wheel on a shaft? Would have to be in a vacuum.
Ok wait, the answer is yes. Consider a horizontal beam attached at one end that is 6 ft long. If a force (x) is applied at the end of it in the downward direction and another force is applied that is twice as powerful (2x) in the upward direction 3 ft from the attached end the net torque is zero but the net force is x in the upward direction.

What would happen to an object when normal force and force of gravity is applied?
When a normal force and force of gravity act on an object, the object will either remain stationary if the forces are balanced, or accelerate in the direction of the unbalanced force if there is a net force acting on it. The normal force is perpendicular to the surface the object is in contact with, while the force of gravity acts vertically downward towards the center of the Earth.
What are anticlockwise and clockwise equilibrium?
Anticlockwise equilibrium refers to a state where the net torque acting on an object causes it to rotate counterclockwise, while clockwise equilibrium refers to a state where the net torque causes the object to rotate clockwise. In both cases, the object is in rotational equilibrium because the torques are balanced and there is no angular acceleration.
Which of these would change the direction of an object but not affect the object's speed?
Changing an object's direction without affecting speed requires a force that acts perpendicular to the object's velocity, such as centripetal force or gravitational force. This force causes the object to change direction while continuing at a constant speed. Other forces acting parallel to the object's velocity can change its speed as well as its direction.
What happens when an unstopabul force meat an emovebal object?
Obviously you can't have both an unstoppable force and an immovable object. If the force moves the object, then the object isn't unmovable. If the force doesn't move it, then the force isn't unstoppable.
When the net force on an object is zero what will the object in motion do?
The object will remain at rest if it was at rest or will maintain its motion with uniform velocity if it was moving.
Compare the effects of force and a torque exerted on an object?
Force and torque are both ways to apply a push or pull on an object. However, force is a linear push or pull that causes an object to move in a straight line, while torque is a rotational force that causes an object to rotate around an axis. Forces can cause translational motion, while torques can cause rotational motion.
What is the Difference between comprensinve force and tensile force?
Compressive force is a force that tends to compress or shorten an object, while tensile force is a force that tends to stretch or elongate an object. In other words, compressive force pushes inward on an object, while tensile force pulls outward on an object.
What is the difference between a push and a pull force?
A push force is when an object is pushed away from the force, while a pull force is when an object is pulled towards the force.
What is the difference between a force and an unbalanced force?
Balanced force means that the sum (vector sum) of all forces on an object is zero. Unbalanced means it's not.
What happens when a force is applied to an object while the object moves in a direction opposite to the force?
When a force is applied to an object in the opposite direction of its motion, the object will slow down. The force will act as a decelerating force, causing the object to lose speed and eventually come to a stop if the force continues to be applied.
What is the difference between centrifugal and centripetal force and how do they affect the motion of an object?
Centrifugal force is the outward force experienced by an object moving in a circular path, while centripetal force is the inward force that keeps the object moving in a circular path. Centrifugal force pushes an object away from the center of rotation, while centripetal force pulls it towards the center. These forces work together to keep an object in circular motion, with centripetal force balancing out centrifugal force to maintain the object's path.
What is the difference between centrifugal and centripetal force, and how do they relate to the concept of centrifugal vs centrifugal acceleration?
Centrifugal force is the outward force experienced by an object moving in a circular path, while centripetal force is the inward force that keeps the object moving in a circular path. Centrifugal force is a perceived force that arises from the object's inertia, while centripetal force is the actual force that keeps the object in its circular motion. Centrifugal acceleration is the apparent outward acceleration experienced by an object in circular motion, while centripetal acceleration is the actual inward acceleration that keeps the object moving in a circle.
How the reaction force will act on an object while pulling and pushing the object placed on a table?
When pulling an object on a table, the reaction force will be equal and opposite to the pulling force exerted on the object. When pushing an object on a table, the reaction force will be equal and opposite to the pushing force exerted on the object. In both cases, the table exerts a reaction force to prevent the object from moving.
What are the two ways you can apply a force to an object?
you can push the object or you can pull the object
What is the relationship between centripetal force and the rotational force?
Centripetal force is the force required to keep an object moving in a circular path, while rotational force is the force that causes an object to rotate around an axis. In the context of circular motion, centripetal force is responsible for maintaining the circular path, while rotational force contributes to the rotation of the object.
What is the difference between centripetal force and inertia?
Centripetal force is the force directed towards the center of a circular path that keeps an object moving in a circle, while inertia is the tendency of an object to resist changes in its state of motion. Inertia is a property of an object, while centripetal force is the external force required to keep an object moving in a curved path.
What occurs when while the force is acting on an object?
When a force is acting on an object, it can cause the object to accelerate, decelerate, change direction, or deform depending on the magnitude and direction of the force relative to the object's mass and shape. The object's velocity and momentum may also change as a result of the force.
