Question

For a given mass m, linear velocity v, linear displacement s, linear acceleration a and time t, the dimensionally INCORRECT expression for power P is

• A. \(\frac{1}{2} mav\)
• B. \(\frac{mv^2}{t}\)
• C. \(\frac{1}{2} mv^2\)
• D. \(ma^2 t\)

Hint:

Power is Energy/Time. Always check if the expression looks like a known energy term divided by time. Since \(\frac{1}{2}mv^2\) is exactly the formula for kinetic energy, it cannot also be the formula for power.

Answer 1

The Correct Option is C
