What are Newton's Three Laws of Motion? - (ANSWER)1: an object at rest will remain at rest
unless acted upon by an unbalanced force (inertia)
2: force x mass = acceleration (force)
3: for every action there is an equal and opposite reaction (action reaction)
what is the SI unit for force - (ANSWER)newton
what is the formula for force - (ANSWER)F=ma
First Law of Motion (Law of Inertia) - (ANSWER)An object in motion stays in motion while an
object at rest stays at rest
Second Law of Motion (Law of Acceleration) - (ANSWER)The acceleration of an object is
directly proportional to the force acting on it and is inversely proportional to its mass. The
direction of the acceleration is in the direction of the applied force.
Third Law of Motion (Law of Action and Reaction) - (ANSWER)For every action there is an
equal and opposite reaction
weight - (ANSWER)A measure of the gravitational force exerted on an object.
weight is the product of - (ANSWER)it's mass and the acceleration of gravity
even though weight may change due to the value of gravity acting upon it, mass _____ -
(ANSWER)does not change
momentum is the product of - (ANSWER)mass and velocity
