What else can I help you with?
Can a force at any angle perform work?
certainly. The force vector can be resolved into one component parallel to the motion of the object under force and another component perpendicular to the motion. The parallel component does the work; the perpendicular component does no work
What should be the angle between the direction of force and the direction of motion of a body so that the work done is zero?
If the angle between the force and the direction of motion of a body is 90 degrees (perpendicular), then the work done is zero. This is because the component of force in the direction of motion is zero, resulting in no work being done on the object.
Force at what direction of motion can perform work?
Work is "defined " as force in the direction of displacement or fdcos(angle), so if the angle is zero the work is maximum. A better definition is to realize that work is the product of force times displacement w=fd= -fdcos(a) + fdsin(A). Here we see that there is real work -fdcos(A)and vector work (commonly called torque) fdsin(A). Notice also that work is negative at angle zero, force and displacement in the same direction and work is positive when the direction is opposite. The differnece in sign is exergy or energy.
What happens to the direction of motion of the ball what changes it direction of motion?
The direction of motion of a ball changes when an external force acts on it, such as a kick or a collision with another object. This force causes the ball to accelerate or decelerate in a different direction than its initial path.
When you push a crate with N across a M floor how much work is done?
The work done when pushing a crate with a force N across a distance M on a floor depends on the angle between the force and the direction of motion. If the force is applied in the same direction as motion, work done is N * M. If the force is applied at an angle, work done is N * M * cos(theta), where theta is the angle between the force and direction of motion.
Can a force at any angle perform work?
certainly. The force vector can be resolved into one component parallel to the motion of the object under force and another component perpendicular to the motion. The parallel component does the work; the perpendicular component does no work

What is the angle between the direction of motion of an object and the direction of the applied force if the work done on the object is said to be negative?
If the work done on an object is negative, the angle between the direction of motion and the direction of the applied force is greater than 90 degrees. This means the force is acting in the direction opposite to the motion of the object, resulting in a decrease in energy or displacement of the object in the opposite direction of the force.
What happens to the direction of motion of the ball what changes it direction of motion?
The direction of motion of a ball changes when an external force acts on it, such as a kick or a collision with another object. This force causes the ball to accelerate or decelerate in a different direction than its initial path.

The work done when pushing a crate with a force N across a distance M on a floor depends on the angle between the force and the direction of motion. If the force is applied in the same direction as motion, work done is N * M. If the force is applied at an angle, work done is N * M * cos(theta), where theta is the angle between the force and direction of motion.
Diagram for how COS theta times distance and force equals work?
Work is equal to the product of the force applied in the direction of motion, the distance over which the force is applied, and the cosine of the angle between the force and the direction of motion. Mathematically, it can be represented as W = F * d * cos(θ), where W is work, F is force, d is distance, and θ is the angle between the force and the direction of motion.
What must be applied to an object to change its direction?
A force must be applied to an object in order to change its direction. By exerting a force at an angle to the object's initial direction of motion, the object will change its path and move in a different direction.
On the pail when the person is holding the pail by the force F is moving forword how much work is done?
The work done when a person is holding a pail and moving forward by a force F is given by the formula: Work = Force x Distance x cos(theta), where theta is the angle between the force and the direction of motion. If the force is directly in line with the direction of motion (theta = 0), then all of the force is doing work. If the force is at an angle to the direction of motion, only the component of the force in the direction of motion contributes to the work done.
What list shows what can happen to the motion of an object when only one force is acting on the object?
When only one force is acting on an object, the motion of the object can include acceleration, deceleration, or a change in direction. The object may speed up if the force is in the same direction as the object's initial motion, slow down if the force is in the opposite direction, or change direction if the force is at an angle to the motion.
Why force have cosine value?
If a force is acting at an angle to the direction of motion then it is usually helpful to study components of the force along the line of motion and at right angles to it. For a force of magnitude f, acting at an angle x with the line of motion, the component along that line is f*cos(x).
What is a sideways force?
A sideways force is a force that is applied in a direction that is perpendicular to the direction an object is moving or the direction of an object's orientation. This force can cause the object to change its direction of motion or orientation. An example of a sideways force is a gust of wind pushing a sailboat to the side.
