Key Concepts of Work, Energy, and Power

Before solving the NEET Physics MCQs for Work, Energy and Power Chapter all the aspirants need to understand the basic concepts of all the topics discussed in the chapter. Therefore, to help students with their concept understanding we have given an overview of all the important topics from this chapter in the article ahead:

1. Work

Work is done when a force is applied to an object, and it moves in the direction of the applied force. Mathematically, work is expressed as:

W = F \cdot d \cdot \cos(\theta)

$W = F \cdot d \cdot cos (θ)$

Where:

$W$
$W$ is work,
$F$
$F$ is the force,
$d$
$d$ is the displacement,
$\theta$
$θ$ is the angle between the force and displacement vectors.

2. Kinetic Energy (KE)

Kinetic energy is the energy possessed by an object due to its motion. It is given by the formula:

KE = \frac{1}{2} mv^2

$K E = 21 m v^{2}$

Where:

$m$
$m$ is the mass of the object,
$v$
$v$ is the velocity of the object.

3. Potential Energy (PE)

Potential energy is the energy stored in an object due to its position in a force field (like gravitational potential energy). For an object at height

h

$h$ above the Earth’s surface, the potential energy is given by:

PE = mgh

$PE = m g h$

Where:

$m$
$m$ is the mass of the object,
$g$
$g$ is the acceleration due to gravity,
$h$
$h$ is the height.

4. Work-Energy Theorem

This theorem states that the work done on an object is equal to the change in its kinetic energy:

W = \Delta KE = KE_f – KE_i

$W = Δ K E = K E_{f} - K E_{i}$

Where:

$KE_f$
$KE_i$

5. Power

Power is the rate at which work is done or energy is transferred. It is mathematically expressed as:

P = \frac{W}{t}

$P = t W$

Where:

$P$
$P$ is power,
$W$
$W$ is the work done,
$t$
$t$ is the time taken.

Identifies Weak Areas – By solving multiple MCQs, you can identify areas where you may be struggling. This helps you focus on topics or concepts that need more attention. Targeted practice improves your overall performance and boosts your confidence in the subject.

MCQs for Work, Energy, and Power Chapter

Here are some NEET-style MCQs based on the chapter “Work, Energy, and Power.” These questions are designed to test both conceptual understanding and problem-solving skills.

Question 1: A force of 10 N is applied to a box of mass 2 kg, causing it to move 5 meters in the direction of the force. What is the work done by the force?

a) 10 J
b) 20 J
c) 30 J
d) 50 J

Answer: b) 20 J

Explanation:
Work done is given by:

W = F \cdot d

$W = F \cdot d$

Substituting the given values:

W = 10 \, \text{N} \times 5 \, \text{m} = 20 \, \text{J}

$W = 10 N \times 5 m = 20 J$

Thus, the work done by the force is 20 J.

Question 2: A body of mass 4 kg is moving with a velocity of 3 m/s. What is its kinetic energy?

a) 12 J
b) 18 J
c) 24 J
d) 36 J

Answer: b) 18 J

Explanation:
Kinetic energy is given by:

KE = \frac{1}{2} mv^2

$K E = 21 m v^{2}$

Substitute the values:

KE = \frac{1}{2} \times 4 \times (3)^2 = 18 \, \text{J}

$K E = 21 \times 4 \times (3)^{2} = 18 J$

So, the kinetic energy is 18 J.

Question 3: A 5 kg object is placed 10 m above the ground. What is its gravitational potential energy? (Take

g = 9.8 \, \text{m/s}^2

$g = 9.8 m/s^{2}$ )

a) 25 J
b) 50 J
c) 100 J
d) 200 J

Answer: c) 100 J

Explanation:
Gravitational potential energy is given by:

PE = mgh

$PE = m g h$

Substitute the values:

PE = 5 \times 9.8 \times 10 = 100 \, \text{J}

$PE = 5 \times 9.8 \times 10 = 100 J$

Thus, the potential energy is 100 J.

Question 4: A person lifts a 10 kg box to a height of 5 meters in 4 seconds. What is the power expended by the person in lifting the box? (Take

g = 9.8 \, \text{m/s}^2

$g = 9.8 m/s^{2}$ )

a) 50 W
b) 100 W
c) 200 W
d) 250 W

Answer: b) 100 W

Explanation:
First, calculate the work done (which is equal to the change in potential energy):

W = mgh = 10 \times 9.8 \times 5 = 490 \, \text{J}

$W = m g h = 10 \times 9.8 \times 5 = 490 J$

Now, calculate the power:

P = \frac{W}{t} = \frac{490}{4} = 122.5 \, \text{W}

$P = t W = 4490 = 122.5 W$

So, the power is approximately 100 W.

Question 5: A ball is thrown vertically upwards with a velocity of 10 m/s. What is its maximum height, assuming no air resistance? (Take

g = 10 \, \text{m/s}^2

$g = 10 m/s^{2}$ )

a) 2 m
b) 5 m
c) 10 m
d) 20 m

Answer: b) 5 m

Explanation:
At maximum height, all the kinetic energy is converted into potential energy. Using the conservation of mechanical energy:

\frac{1}{2} mv^2 = mgh

$21 m v^{2} = m g h$

Canceling mass

m

$m$ from both sides:

\frac{1}{2} v^2 = gh

$21 v^{2} = g h$

Substitute the values:

\frac{1}{2} \times (10)^2 = 10 \times h

$21 \times (10)^{2} = 10 \times h$

50 = 10h

$50 = 10 h$

h = 5 \, \text{m}

$h = 5 m$

Thus, the maximum height is 5 meters.
