Study Notes

This is a physics exam paper with 75 marks and a time limit of 76 minutes.
The paper includes questions about power, energy transfers, kinetic energy, gravitational potential energy, and electric motors.
There are diagrams and tables provided to aid in answering the questions.
The paper emphasizes the importance of appropriate equipment and energy efficiency.
Students are asked to calculate power, energy stored, and gravitational potential energy.
They are also asked to identify variables and draw conclusions from data.
The paper includes questions about the relationship between load and input energy and the cost of electricity.
The drone is mentioned as an example of energy transfer.

The energy store of a drone's battery decreases as it flies.
Flying a drone too high above the ground in the USA is not allowed due to potential risks.
The equation linking energy transferred, power, and time is not provided.
Miners in a salt mine use wooden slides to move between levels.
The change in gravitational potential energy of a miner moving 15m vertically downwards is calculated using gravitational field strength.
The maximum possible speed a miner could reach at the bottom of the slide is calculated.
The velocity of an object includes both its speed and direction.
The kinetic energy gained by a student during a bungee jump is calculated.
The rocket's velocity and speed are different.
The kinetic and gravitational potential energy of a rocket just after launch are calculated.
The problem involves a rocket launched vertically with no air resistance.
Gravitational field strength is 10 N/kg.
The task is to find the maximum height the rocket will reach.
Four velocity-time graphs are shown in Figure 2.
The question asks which graph shows the velocity of the rocket as it falls to the ground.
The rocket can be launched at different angles to the horizontal.
The horizontal distance the rocket travels is called the range.
Figure 3 shows the paths taken by the rocket when launched at different angles.
The task is to find the pattern linking the angle of launch and the range of the rocket.
The total marks for the task are 11.
