Question

Imagine a ball flying through the air. Define this ball as a closed system. An external force is applied to the ball, changing its direction and speed. From the following list, select the statements that are true. The work done by the force causes a change in potential energy of the ball. The force applied to the ball results in an energy transfer to the ball as work. The force applied to the ball results in a heat transfer to the environment. The work done by the force causes a change in kinetic energy of the ball. Following the sign convention in our textbook for work and heat transfer, select from the list below the correct versions of the 1st Law of Thermodynamics for a CLOSED system. delta E = Q - W dE = dQ - dW delta E = W - Q delta E = Q - W dE = delta Q - delta W dE/dt = Q - W

Explanation / Answer

For question 2, the correct options are

The force applied to the ball results in an energy transfer t the ball as work

The work done by the force causes a change in kinetic energy of the ball
