A force is needed to move an object.
kinetic frictional
Yes, an unbalanced force is needed to change the motion of an object.If an unbalanced force does not act on an object it will continue to maintain its state of motion (either in motion or at rest), not considering the effect of frictional force. This is basically Newtons first law of motion.
Increasing the number of pulleys divides the force required to lift up a heavy object; increasing the number of pulleys decreases the force needed by the person (or motor) pulling the first end of the pulley system. However, it is important to know that it does not affect the total work needed to lift up the object. As the force is decreased, the distance of rope needed increases to compensate for a conserved amount of work required for the load to be lifted.
The force that keeps objects moving in a circle is known as the centripetal force, which acts towards the center. The velocity of the object moving in a circle will be tangential to the circle.
A force is the total force felt by an object
buoyant force.
In symbols, when the applied force ( F_{\text{applied}} ) is equal to the frictional force ( F_{\text{friction}} ), then the net force ( F_{\text{net}} ) is zero, and the object will travel with a constant velocity. This means that there is no acceleration, and the object maintains its state of motion.
Weight is the force acting on an object due to gravity.
Net force determines the motion of the object. If the net force acting on an object is not zero, the object will accelerate in the direction of the net force.
Inertia.
overcome
An inclined plane reduces the amount of force needed to move an object by increasing the distance over which the force is applied, which decreases the force required. This is because the force needed to lift an object vertically is greater than the force needed to push it along an inclined plane.
The buoyant force determines whether an object will float. This force is equal to the weight of the fluid displaced by the object, and if the buoyant force is greater than the object's weight, the object will float.
A pulley is a simple machine that changes the direction of the force needed to move an object without changing the amount of force required. By using a pulley, you can apply a downward force to lift an object upwards.
The force needed to stop a moving object is equal to the object's mass multiplied by its acceleration. This force is generated by applying a force in the opposite direction to the object's motion, causing it to decelerate until it comes to a complete stop.
The type of force needed to overcome the inertia of an object is an external force. Inertia is the tendency of an object to resist changes in its motion, so an external force is required to overcome this resistance and cause the object to move.
The frictional force needed to start an object at rest into motion is the static frictional force. This force must be overcome by an external force before the object can start moving. Once the object is in motion, the kinetic frictional force will oppose its movement.
