Explain what is the negative sign in hook's law mean?
It means that the force is in a direction opposite to the displacement of the spring.It means that the force is in a direction opposite to the displacement of the spring.It means that the force is in a direction opposite to the displacement of the spring.It means that the force is in a direction opposite to the displacement of the spring.
Work is the product of and an object's displacement?
Work is the product of force and displacement, where force is the effort applied to move an object and displacement is the distance the object moves in the direction of the force. The formula for work is: Work = Force x Displacement x cos(theta), where theta is the angle between the force and displacement vectors.
What is the formula for calculating work done when a force is applied in the direction of motion, involving the product of the force and the displacement, represented by the keyword r cross f?
The formula for calculating work done when a force is applied in the direction of motion is W F d cos(), where W is the work done, F is the force applied, d is the displacement, and is the angle between the force and the direction of motion.
The application of a force through a distance?
Work = Force * displacement if the displacement and the force are parallel - work is positive if force and displacement are in the same direction, negative if they have opposite direction. At an angle Work = Force * displacement * cos(θ) where θ is the angle between the force and displacement vectors.
How do we calculate the restoring force according to Hookes law?
According to the Hooke's law formula, the force is proportional to what measurement
What do you call a force multiplied by displacement?
The product of force and displacement is called work. Work is calculated as force times displacement in the direction of the force.
What is the formula for solving work?
The formula for work is work = force x distance x cos(theta), where force is the applied force, distance is the displacement over which the force is applied, and theta is the angle between the force and the direction of motion.
Why is it that no work is done when the force and the displacement are perpendicular to each other?
When a force and displacement are perpendicular to each other, no work is done because the force is not acting in the same direction as the displacement. Work is defined as the product of force and displacement in the direction of the force, so when they are perpendicular, the force does not contribute to the displacement and no work is done.
What angle do you use in work equation?
In the work equation, the angle used is the angle between the direction of the force applied and the direction of displacement. The work done (W) is calculated using the formula ( W = F \cdot d \cdot \cos(\theta) ), where ( F ) is the magnitude of the force, ( d ) is the displacement, and ( \theta ) is the angle. If the force is in the same direction as the displacement, ( \theta ) is 0 degrees, and the work done is maximized. If the force is perpendicular to the displacement, the work done is zero.
What is required for a force to do work on an object?
in the same direction as the object's motion.
When force is perpendicular to the direction of motion no work is done ture or false?
True. When the force is perpendicular to the direction of motion, no work is done because work is the product of force and displacement in the direction of the force. Since there is no displacement in the direction of the force, no work is done.
Why the formula of work done obliquely is F s cos Ө?
Because work done is equal to the force times the distance travelled IN THE DIRECTION of the force. Distance travelled in an oblique direction can be decomposed into two components: s*cos(x) in the direction of the force and s*sin(x) in a direction perpendicular to it (where x is the angle between the force and the resultant motion). Motion in a perpendicular direction is NOT work done by the force, which leaves s*cos(x). Multiply by the force (as required) and you have your answer.
