- Describe the forces acting on a skydiver over time, from the moment she jumps out of the plane until hitting the ground and the effect this has on her velocity. What happens when she opens her parachute?
- What's the difference between a vector and a scalar?
- A roller coaster car starts stationary at the top of a downwards slope. At the bottom of the slope, it has a speed of 30m/s. Use the conservation of energy to find the vertical height of the slope. (Use g=10 m/s^2)
- What is the structure of atoms
- A ball is dropped from a height of 20m. How long does it take for the ball to reach ground?
