Motion, forces, and energy
Describes the location of an object.
What is position?Describes the location of an object.
The speed at which velocity changes
What is acceleration?
A push or a pull.
What is a force?
A force of attraction between objects due to their mass.
What is gravity?
Any material that can flow and takes the shape of its container.
What is a fluid?
A location to which you compare other locations.
What is a reference point?
Acceleration in a circular motion.
What is centripital acceleration?
The combination of all the forces acting on an object.
What is a net force?
An attractive force.
What is gravity?
The measure of how much force is acting on a given area.
What is pressure?
A change in position over time.
What is motion?
Expressed in meters per second.
What is velocity?
When the net force is not 0.
What is an unbalanced force?
Distance and mass.
What does gravity depend on?
The S.I. unit for pressure.
What is the pascal?
A measure of how far something moves in a given amount of time.
What is speed?
Measured in seconds.
What is time measured with?
The tendency of all objects to resist a change in motion.
What is inertia?
When gravity is acting on something and no other forces are interacting with it.
When is an object in free fall?
The pressure caused by the weight of the atmosphere.
What is atmospheric pressure?
A quantity that has both size and direction.
What is velocity?
An increase in velocity.
What is acceleration?
For every action, there is a positive reaction.
What is Newton's third law?
When an object travels around another object in space.
What is orbit?
The atmosphere and water.
