## What are two conservative forces?

The most familiar conservative forces are gravity, the electric force (in a time-independent magnetic field, see Faraday’s law), and spring force.

### What exactly is a conservative force conserving Mcq?

A conservative force is one, like the gravitational force, for which work done by or against it depends only on the starting and ending points of motion and not on the path is taken.

#### What are conservative forces List 2 properties of it?

Expert Answer:

- (1) Work done by or against conservative force depends only on the initial and final positions of the body.
- (2) Work done by or against a conservative force in a round trip is zero.
- (3) Work done by a conservative force is completely recoverable.

**How does the work done by a conservative force compare to the change in potential energy caused by the same force *?**

How does the work done by a conservative force compare to the change in potential energy caused by the same force? Select two correct answers. When the force does negative work, the potential energy of the object decreases. The potential energy of the object increases when the force does negative work.

**How do you know if a force is conservative?**

Summary. A conservative force is one for which the work done is independent of path. Equivalently, a force is conservative if the work done over any closed path is zero. A non-conservative force is one for which the work done depends on the path.

## Is tension a non-conservative force?

Tension is a non-conservative force, and therefore has no associated potential energy. When tension is internal, however, it is a non-dissipative force, performing zero net work on the chosen system. Thus, the work done on the two objects will cancel by Newton’s Third Law.

### When work done by a conservative force is positive?

If work done by conservative forces is positive, kinetic energy will increase.

#### What exactly is a conservative force conserving *?

A conservative force is a force done in moving a particle from one point to another, such that the force is independent of the path taken by the particle. It depends only on the initial and final position of the particle. Gravitational force and elastic spring forces are two such examples of conservation forces.

**What is conservative force class11?**

Conservative forces are those for which work done depends only on initial and final points. Example- Gravitational force, Electrostatic force. Non-Conservative forces are those where the work done or the kinetic energy did depend on other factors such as the velocity or the particular path taken by the object.

**What is a conservative forces give an example?**

A conservative force exists when the work done by that force on an object is independent of the object’s path. Instead, the work done by a conservative force depends only on the end points of the motion. An example of a conservative force is gravity.

## When conservative force does positive work on a system then potential energy of system?

Thereby, decreasing the potential energy of the body and increasing the kinetic energy of the body. Hence, when a conservative force does positive work on a body, the potential energy decreases. So, the correct answer is option B i.e. the potential energy decreases.

### Is buoyant force a conservative force?

Buoyant force is opposite to gravity in direction. As garvity is a central force (directed inwards) buoyant force is also a central force (directed outwards). Hence it is a conservative force.

If a force has the following properties, then it is said to be a conservative force. When the force only dependent on the initial and final position irrespective of the path taken. In any closed path, the work done by a conservative force is zero. The work done by a conservative is reversible. What is Non-Conservative force?

#### What is the work done by a conservative and non-conservative force?

The work done by a conservative force is independent of the path; in other words, the work done by a conservative force is the same for any path connecting two points: The work done by a non-conservative force depends on the path taken.

**Is the gravitational force a conservative force?**

Hence, the gravitational force is a conservative force. If a force has the following properties, then it is said to be a conservative force. When the force only dependent on the initial and final position irrespective of the path taken. In any closed path, the work done by a conservative force is zero.

**What are some examples of conservative forces?**

Many forces in nature that we know of like the magnetic force, electrostatic force, gravitational force, etc. are a few examples of a conservative force. Let us understand the concept better with the help of the following example.
