Question 1.
What is an equipotential surface?
Show hintHide hint
Think of areas in a gravitational field where energy doesn't change.
Question 2.
Why is no work done when moving along an equipotential surface?
Show hintHide hint
Consider what it means to change energy in a field.
3Question 3.
What is true about equipotential surfaces?
- They are parallel to field lines.
- They are perpendicular to field lines.
- They vary with distance from the mass.
Show hintHide hint
Remember the definition of how these surfaces interact.
4Question 4.
True or False: Moving a mass along an equipotential surface requires work.
- True
- False
Show hintHide hint
Think about potential energy changing as work is done.
Question 5.
If the gravitational potential difference between two points on an equipotential surface is zero, explain what effects this has on an object moving between the two points.
Show hintHide hint
Think about conservation of energy.
Question 6.
Illustrate and describe the shape of equipotential surfaces for a point mass and discuss how this connects to gravitational field strength.
Show hintHide hint
Draw a diagram to visualize the relationship.
