Physic Tuition - Kinematics - 2 (MCQ)

Questions

Solution
C - The velocity of the ball increases because the ball accelerates under gravity. The acceleration on the other hand decrease due to air resistance opposing the gravitational force.

Physic Tuition - Work Energy Power - 1 (MCQ)

Question

Solution
D - This question is a bit tricky. The amount of kinetic energy in this case depends on the energy given to the 3 blocks (F x D) and hence all the 3 blocks have the same kinetic energy.
