Practice Questions
Question 1
A block is pushed up a frictionless incline at a constant speed. Which of the following statements about the work done by the applied force and gravity is true?
Question 2
A pendulum swings from its highest point to its lowest point. At which point is its kinetic energy maximum and its potential energy minimum?
Question 3
A car accelerates from rest to a speed $v$. If the same car then accelerates from speed $v$ to speed $2v$, how does the work done in the second scenario compare to the work done in the first scenario?
Question 4
A block is pulled by a rope across a horizontal surface. If the tension in the rope is $T$ and the rope makes an angle $\theta$ with the horizontal, what is the work done by the tension force over a distance $d$?
Question 5
A spring is stretched by a distance $x$ from its equilibrium position. If the spring constant is $k$, what is the formula for the elastic potential energy stored in the spring?
