A body of mass $ m = 2 \, \text{kg} $ is moving with a velocity of $ 5 \, \text{m/s} $. What is the kinetic energy of the body?
Show Hint
Remember: Kinetic energy is always positive, and the formula is \( \text{Kinetic Energy} = \frac{1}{2} m v^2 \).

- \( 25 \, \text{J} \)
- \( 10 \, \text{J} \)
- \( 50 \, \text{J} \)
- \( 100 \, \text{J} \)
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Apply the kinetic energy formula \[\text{Kinetic Energy} = \frac{1}{2} m v^2\]Parameters provided:- Mass \( m = 2 \, \text{kg} \) - Velocity \( v = 5 \, \text{m/s} \)Calculation:\[\text{Kinetic Energy} = \frac{1}{2} \times 2 \times (5)^2 = 25 \, \text{J}\]Conclusion: The kinetic energy of the object is \( 25 \, \text{J} \). The correct option is (1).

- A curve is given between the potential energy \(U\) of a particle and its position on the \(x\)-axis as shown. Given: \[ \tan\theta_1 = 1,\qquad \tan\theta_2 = 3,\qquad \tan\theta_3 = -\frac{1}{2} \] If \(F_{AB}\) is the force acting on the particle during motion from \(A\) to \(B\), similarly \(F_{BC}\), \(F_{CD}\) and \(F_{DE}\) are the forces during \(B\) to \(C\), \(C\) to \(D\) and \(D\) to \(E\) respectively, arrange the magnitudes of these forces in decreasing order.

- Given below are two statements:
Statement I: An object moves from position \( \vec{r}_1 \) to position \( \vec{r}_2 \) under a conservative force field \( \vec{F} \). The work done by the force is \[ W = -\int_{\vec{r}_1}^{\vec{r}_2} \vec{F} \cdot d\vec{r}. \]
Statement II: Any object moving from one location to another location can follow infinite number of paths. Therefore, the amount of work done by the object changes with the path it follows for a conservative force.
In the light of the above statements, choose the correct answer from the options given below:- JEE Main - 2026
