Worksheet Answers and Guide
Section 1: Energy and Motion
- What type of energy does the skater possess at the top of the ramp?
Answer: Potential energy (PE)
Explanation: At the top of the ramp, the skater has the highest potential energy due to their height above the ground.
- As the skater rolls down the ramp, what happens to their potential energy?
Answer: It decreases
Explanation: As the skater rolls down the ramp, their potential energy is converted into kinetic energy, causing their potential energy to decrease.
- What type of energy does the skater possess at the bottom of the ramp?
Answer: Kinetic energy (KE)
Explanation: At the bottom of the ramp, the skater has the highest kinetic energy due to their motion.
Section 2: Conservation of Energy
- What is the total energy of the skater at the top of the ramp?
Answer: PE + KE = Total Energy
Explanation: The total energy of the skater at the top of the ramp is the sum of their potential energy and kinetic energy.
- What happens to the total energy of the skater as they roll down the ramp?
Answer: It remains constant
Explanation: The total energy of the skater remains constant, as energy is converted from potential to kinetic, but the total energy remains the same.
- What is the relationship between the skater’s potential energy and kinetic energy as they roll down the ramp?
Answer: As PE decreases, KE increases
Explanation: As the skater rolls down the ramp, their potential energy decreases, and their kinetic energy increases, illustrating the conversion of energy from one form to another.
Section 3: Energy Transformations
- What type of energy transformation occurs as the skater rolls down the ramp?
Answer: Mechanical energy → Kinetic energy
Explanation: As the skater rolls down the ramp, their mechanical energy (potential energy + kinetic energy) is converted into kinetic energy.
- What type of energy transformation occurs when the skater collides with the barrier?
Answer: Kinetic energy → Potential energy
Explanation: When the skater collides with the barrier, their kinetic energy is converted into potential energy, causing them to bounce back up the ramp.
- What type of energy transformation occurs when the skater goes up the ramp?
Answer: Kinetic energy → Potential energy
Explanation: As the skater goes up the ramp, their kinetic energy is converted into potential energy, causing them to slow down and come to a stop.
📝 Note: Make sure to adjust the simulation settings to match the worksheet questions. For example, set the "Energy" setting to "Visible" to see the energy bars, and adjust the "Friction" setting to "Low" or "High" to observe the effects of friction on the skater's motion.
