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.
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 is the angle between angular and tangential velocity?
The angle between angular and tangential velocity is 90 degrees. Angular velocity is perpendicular to the direction of tangential velocity in a circular motion.
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.
Why does the acceleration of an object rolled down an incline increase as the angle of incline increases?
The contribution of the acceleration of gravity in the direction of motion increases as the angle of the incline increases. Or in other words, as the angle between the direction of motion and the force of gravity goes to zero, the acceleration of the object goes to the gravitational acceleration. a = g cos(theta) Where theta is the angle between the direction of motion and verticle, which is in fact (theta = 90 - angle of the incline)Where a is the acceleration of the object down the incline plane and g is the acceleration due to gravity. Theta is the angle between the direction of motion of the accelerating object and the acceleration of gravity. Initially, the angle between a and g is 90 degrees (no incline) and therefore g contributes nothing to the objects acceleration. a = g cos(90) = 0 As the angle of the inclined is increased, the angle between a and g approaches zero, at which point a = g. With no other forces acting upon the object, g is its maximum acceleration.
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 is the definition of angle of impact?
The angle of impact is the angle at which an object or force strikes another object. It is measured between the direction of impact and a reference line on the struck object, such as the horizontal plane. The angle of impact can affect the resulting damage or motion of the objects involved.
A force at any angle to the direction of motion can perform work?
Yes, a force can perform work at any angle to the direction of motion. The work done is determined by the component of the force that is in the direction of motion, not the total force itself. This component is what contributes to the displacement of the object and thus the work done on it.
What should be the angle between two vectors acting on a particle in opposite direction?
180 degrees
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.
How do you find magnetic direction?
The angle between the direction your compass points and the direction you're facing is the 'magnetic azimuth'. The angle between the direction to the north pole and the direction you're facing is the 'true azimuth'. They are virtually never the same angle. The difference between them is the 'magnetic declination' or the 'compass declination' in the place where you are at in which.
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.
