Work is directly proportional to the first two factors: force and displacement .
What are the factors that affect work done class 9?
- Magnitude of the force (F), and.
- The displacement through which the body moves (s).
What are the factors that affects the work done?
- Force Acting on the Body: At constant displacement and the constant angle between force and displacement, work is directly proportional to the acting force.
- Displacement of the Body: ...
- The Angle Between Force and Displacement:
What two factors affect work done?
1) The force applied to the particular object. 2) The exact distance in which the body is displaced.
What is work and example?
Work is force applied over distance. Examples of work include lifting an object against the Earth’s gravitation, driving a car up a hill, and pulling down a captive helium balloon . Work is a mechanical manifestation of energy. The standard unit of work is the joule (J), equivalent to a newton – meter (N · m).
What are factors of work?
The seven factors are work load, family life, transportation, compensation policy and benefits, colleagues and supervisor, working environment and working condition and career growth .
What is work done formula?
Mathematically, the concept of work done W equals the force f times the distance (d), that is W = f. d and if the force is exerted at an angle θ to the displacement, then work done is calculated as W = f . d cos θ .
What is force what are the two factors to move things depend on?
Force and Pressure | Short/Long Answer Questions
Solution: Factors on which moment of force depends are: (i) The magnitude of the force applied . (ii) The distance of line of action of the force from the axis of rotation.
What is always done on a body when?
a force acts on body to displace it . it moves through a certain distance. it experiences an increase in energy through a mechanical influence.
What factors affect power?
- Significance level (or alpha)
- Sample size.
- Variability, or variance, in the measured response variable.
- Magnitude of the effect of the variable.
What is the relationship between work and power?
Work is referred to as the process of energy that is transferred to an object’s motion by applying force. It is generally represented as the product of displacement and force. Power is the amount of energy that is transferred in a unit of time. The formula for calculating the force is Work = Force * Displacement.
Do you do work when you raise the ball to 1 meter height?
Do you do work when you raise the ball to 1 meter height? How do you know? Yes. Work is force times distance , and in this case the force is exerted on the ball by your hand to raise the ball a distance of 1 meter.
What is the example of power?
Power is defined as the ability to act or have influence over others. An example of power is the strength needed to run five miles . An example of power is the authority a local government has to collect taxes. Power means to supply with energy or force.
Is walking an example of work?
Even just walking on flat ground is doing some work in the physics sense. Your center of mass will bounce up and down with each step. The up part requires work to be done, and the body has no mechanism to derive energy from joints being moved by external forces, so can’t recover the work on the way down.
What is work short note?
Work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. ... If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ .
