Transitional Motion Flashcards
Velocity equation
Average velocity: the change in position (or displacement) over the total time of travel
velocity vs. acceleration
Velocity is calculated as distance divided by time, while acceleration is the change in velocity divided by the time it takes for that change to occur
velocity = change in pos
Newton’s second law
States when a net force acts on an object, the change in that object’s state of motion will be inversely proportional to the mass (m) of the object and directly proportional to the net force (F) acting on the object. It can be written as F = ma.
Newton’s first law
a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This is also known as the law of inertia. Inertia is the tendency of an object to remain at rest or remain in motion.

Newton’s law of gravitation equation
G = 6.67e-11 Nm²/kg²
m₁ and m₂ are two bodies of mass
r = the distance between the bodies
Newton’s third law of motion
whenever one body exerts a force on a second body, the first body experiences a force that is equal in magnitude and opposite in direction to the force that it exerts. … First, the forces exerted (the action and reaction) are always equal in magnitude but opposite in direction.
