Circular Motion and Gravitation
What mass is determined by calculating the force needed to accelerate an object?
How does gravitational mass differ from inertial mass?
Which of the following quantities is a measure of an object's resistance to changes in its state of motion?
A stationary skateboard begins moving when a person jumps off it backward; what conservation principle does this illustrate?
If two objects have different weights but accelerate equally when falling freely under gravity, what can be inferred about their masses?
What unit is typically used for both inertial and gravitational masses in physics?
What happens to the mechanical (total) energy of a system when no nonconservative forces are doing work on or within that system?
How are we doing?

Which principle explains why an astronaut inside a space station not near any massive body would remain at rest or in uniform motion unless acted on by another force?
If an experiment conducted in a spaceship far from any massive bodies measures the inertial and gravitational mass of an object, why might the values differ from those predicted by classical physics?
If two identical spheres are dropped from the same height in a vacuum, one made of lead and the other of aluminum, and an observer measures their free-fall time to determine whether inertial or gravitational mass affects acceleration due to gravity, what would the outcome indicate about these masses?
