Answer:
The 10 kg rock has more inertia than the other two rocks.
Explanation
Answer:
A. Area under force-time graph & Area under force-displacement graph
Explanation:
To find the impulse or work done the area under force-time graph and area under force-displacement graph will give us these respective values.
Impulse = Force x time
Work done = Force x displacement
When we plot a graph of force and time, the area under it is the impulse.
When a graph of force and displacement is plotted, the area under is the work done.
The potential energy of the model will be the greatest at point C while it will be the least at point E. Option B and D are correct.
<h3>
What is potential energy?</h3>
The potential energy of an object is due to its position. It can be given as the formula,

Where,
- potential energy
- mass
- gravitation acceleration
- height
From the formula since the mass and gravitation acceleration is constant, the potential energy of the model will depend upon the height only.
The potential energy will be greatest at point C because the relative position of the ball is the highest from the earth.
The potential energy will be lowest at point E because the height of the ball is the least in this position.
Therefore, the potential energy of the model will be the greatest at point C while it will be the least at point E.
