The rate at which the velocity of an object changes
average acceleration
acceleration
Displacement
Free-fall acceleration
The change in an object's velocity during a measurable time interval divided by that specific time interval; measured in m/s2
Average velocity
Average acceleration
Instantaneous acceleration
Centripetal acceleration
The motion of an object when air resistance is negligible and the motion can be considered due to the force of gravity alone.
Free-fall accleration
Free-fall
Average acceleration
Instantaneous acceleration
The change in an object's velocity at a specific instant in time.
Average accleration
Instantaneous accleration
Negative accleration
Equilibrium
A graph that has velocity plotted on the vertical axis and time plotted on the horizontal axis; its slope is the acceleration of the object whose motion is described by the graph.
Positon-time graph
Distance-time graph
Acceleration-time graph
Velocity-time graph
The acceleration of an object due only to the effect of gravity.
Free fall
Free-fall acceleration
Terminal velocity
Gravitational acceleration
Newton's first law of motion
States that an object at rest will remain at rest and a moving object will continue moving in a straight line with constant speed, if and only if the net force acting on an object is zero.
States that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated.
States that the angular acceleration of an object is directly proportional to the net torque on it and inversely proportional to its moment of inertia.
States that all forces come in pairs and that the two forces in a pair act on different objects, are equal in strength, and are opposite in direction.
Newton's second law of motion
States that an object at rest will remain at rest and a moving object will continue moving in a straight line with constant speed, if and only if the net force acting on an object is zero.
States that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated.
States that the angular acceleration of an object is directly proportional to the net torque on it and inversely proportional to its moment of inertia.
States that all forces come in pairs and that the two forces in a pair act on different objects, are equal in strength, and are opposite in direction.
Newton's third law of motion
States that an object at rest will remain at rest and a moving object will continue moving in a straight line with constant speed, if and only if the net force acting on an object is zero.
