What is the relationship between potential energy and conservative force?
Definition: Change in Potential Energy The change in potential energy of a body associated with a conservative force is the negative of the work done by the conservative force in moving the body along any path connecting the initial and the final positions.
Is the spring force a conservative force?
vs. If the work done by a force depends only on initial and final positions, not on the path between them, the force is called a conservative force. Gravity force is “a” conservative force. “Spring force” is another conservative force.
How elastic spring force is conservative force?
Note that it doesn’t matter at all how the body moves. We only need to know the amount the spring is stretched or compressed from its equilibrium position (as it moves from A to B) to determine the work done by the spring on the body. Therefore, an elastic spring is a conservative force.
Why elastic forces are not always conservative?
Elastic forces are strictly conservative only when Hooke’s law is obeyed. False because elastic forces are not always conservative. Elastic forces are conservative as long as the loading and deloading curves are coincident, even if the curves are not linear. For example rubber.
Which of these options is correct about elastic force?
Answer. Elastic forces may be conservative in nature in the cases where Hooke’s is not obeyed is the correct alternative. Answer: Option d.
Are the elastic restoring force conservative in nature?
The elastic restoring force is a conservative force hence we can associate to it an elastic potential energy.
Are elastic forces Conservative beyond proportionality limit?
Reason:- Elastic forces can be conservative even beyond proportional limit. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
Is Hooke’s Law a conservative force?
is called the force constant of the spring. It follows that the spring force is another example of a conservative force. …
Which of the following statement is true 1 electrostatic force is a conservative force?
Work done by the electrostatic force is independent of the path followed by it, and it depends only on the initial and final positions. For example, work done in moving a unit positive charge in a closed loop of an electric field is zero. So,electrostatic force is a conservative force.
Which of the following statement is true about Hooke’s Law?
Notes: According to this law, within the elastic limit, stress is directly proportional to the strain. Therefore, Stress/Strain = constant and is known as modulus of elasticity.
