Formula for speed
V=d/t
Newton's First Law of Mortion
Law of Inertia
An object in motion tends to stay in motion. And object at rest tends to stay at rest.

Aristotle's contribution to Newton's First Law
All motion is due to the nature of the moving object or a sustained push or pull
Objects will remain at rest until acted upon
Galileo's contribution to Law of Inertia …show more content…

At rest, stays at rest
Newton's contribution to establishing Newton's First Law
Took Galileo's idea, put his name on it.
Newton's Second Law.
Acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force.
Acceleration = net force/mass
Relationship between mass and weight.
Mass - related to amount of matter in an object
Weight - force of gravity acting on mass
Newton's Third Law of Motion
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first
To every action there is an equal and opposite reaction
What four conditions do all forces satisfy?
Occur in pairs
Equal in strength
Opposite directions
Two different objects
Free fall
Acceleration of an object due to gravity
32 ft/sec/sec
9.8 m/sec/sec
Does the force of gravity on an object depend on its mass? Its motion?
No and
