A&R - Kinetic energy and Work and energy — task. Physics CBSE Live product, Class 9 (2026-27).

Evaluate the following Assertion and Reason:

1. Assertion (A): A truck and a bicycle moving at the same speed have the same kinetic energy.

Reason (R): Kinetic energy depends on both mass and velocity.

Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
Assertion (A) is true, but Reason (R) is false.
Assertion (A) is false, but Reason (R) is true.

2. Assertion (A): A heavier object always has greater kinetic energy than a lighter object.

Reason (R): Kinetic energy depends on both mass and velocity.

Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
Assertion (A) is true, but Reason (R) is false.
