Question

please provide explanation if possible.

For each of the following statements determine whether it is correct or incorrect. Coect The kinetic energy is always positive. IncorrectThe work done to raise a box onto a platform depends on how fast it is raised. ctThe kinetic energy depends on the reference frame of the observer. Incorrect If the Earth revolves around the sun in a perfectly circular orbit, then the sun does ncorrectSpring A and B are identical except that A is stiffer than B; that is kA> KB. More work Correct The kinetic energy of an object is independent on the direction of the motion involved work on the Earth. must be expended on spring A if both springs are stretched by the same amount.

Explanation / Answer

1. Correct

2. correct ( More Work is done, if K.E. is more)

3. Correct (Based on relative velocity)

4. Incorrect (Since Gravitational Force is perpendicular to displacement)

5. Correct ( Based on the formula of Work done = 0.5 K X2

6. Correct ( Kinetic Energy is scalar Quantity)
