Is work done independent of initial velocity?

Work done according to its formulaic definition is a product of F (applied force) and d (distance moved in the direction of applied force). Based upon this formulaic definition we can say that Work done has independent of the velocity of an object.

What does the work you do depend on?

The amount of work done on an object depends on the amount of force exerted on the object and the amount of distance the object moves. According to Newton’s Second Law of Motion, the net force on an object is dependent on the mass of the object, and its acceleration during the movement.

How are work and velocity related?

work is a differential equation: dW = Fdx, a differential work unit equals a force acting over a differential distance. Velocity is the instantaneous rate of change of position. thus, the differential work element equals the product of mass, velocity & differential velocity. delta (1/2 mv^2) = W , in terms of Work.

Does kinetic energy depend on initial velocity?

Squaring the value inside the parenthesis we get KE = 0.5 kg * 4 m^2/s^2 which is equal to 2 joules. The ratio of the KE of 2 joules to 0.5 joule is 4 which connotes that doubling the velocity will increase the KE of a body to four times its original KE. It doesn’t… because that implies a cause and effect relationship.

Does work done depend on the velocity?

No, work done by force at any instant does not depend upon the velocity at that instant. Work is dependent on the force and displacement.

On which factors work done depends how they affect work?

Work done by a force depends on (i) magnitude of force (ii) magnitude of displacement (iii) angle between force applied and displacement .

What are the factors affecting work done on an object?

There are three key ingredients to work – force, displacement, and cause. In order for a force to qualify as having done work on an object, there must be a displacement and the force must cause the displacement.

Does work depend on velocity?

Does initial velocity affect work?

No. The force needed for acceleration depends on the mass of the object, and does not depend on its initial velocity.

What factors does the kinetic energy of an object depend on?

Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed. Have students complete this demonstration to learn how mass influences an object’s kinetic energy.

How do kinetic energy affects the amount of work the object can do?

According to the work-energy theorem, the work done on an object by a net force equals the change in kinetic energy of the object. Essentially kinetic energy is the energy used for motion. When things move, they can do work.

What is the work done by an object with constant velocity?

Work done depend upon the change in velocity of the body. If there is no change in velocity , ( constant velocity), no work is done either on the body or by the body. Any object moves with constant velocity, only when the net force acting on the body is zero. Work is force * displacement.

What is work done if there is no change in velocity?

Government of Tamilnadu, lndia. Work done depend upon the change in velocity of the body. If there is no change in velocity , ( constant velocity), no work is done either on the body or by the body. Any object moves with constant velocity, only when the net force acting on the body is zero.

How do you find the kinetic energy of a moving object?

Identify “Speed” with “Velocity”. Power = Force * velocity = Work / time -> Force * time *velocity = Force * Displacement, first equation is true if you have linear motion (v = const). On the other hand Kinetic energy is also work which could be done by an object with some velocity and E(k) = 1/2*m*v^2.

When you accelerate an object you are changing its velocity?

When you accelerate an object, you are changing its velocity. When you accelerate an object, you are doing work against inertia plus any resistive forces—such as gravity or friction—over the distance that the object is accelerated.
