What is the difference between inertial and gravitational mass?
Inertial mass measures resistance to acceleration; gravitational mass measures interaction with gravity. They have the same value.
Compare inertial and non-inertial frames of reference.
Inertial frame: object at rest or constant velocity, laws of physics are the same. Non-inertial frame: object accelerating, fictitious forces may be experienced.
What is a vector field?
A map showing the magnitude and direction of a quantity at different points in space.
Define uniform circular motion.
Movement in a circle at a constant speed.
What is centripetal force?
The net force that keeps an object moving in a circular path, directed towards the center of the circle.
Define gravitational force.
The force of attraction between objects with mass.
What is inertial mass?
A measure of an object's resistance to acceleration.
What is gravitational mass?
A measure of how strongly an object interacts with gravity.
