law of motion Flashcards
objects in motion stay at rest — unless acted upon will stay in motion, and objects at rest will an unbalanced force.
(first law)
the law of inertia
states that the — of an object with constant mass is proportional to the net force action on it and it is in the
same direction of the net force.
(second law)
the law of acceleration
Every action force has a reaction force
that is equal in size and opposite in direction.
(third law)
the law of action and reaction
ex. The golf hall will remain on the grand until the golfer hits it.
(first law)
the law of inertia
ex: The car accelerates forward since the force due to its engine is greater than the friction on the road.
(second law)
the law of acceleration
ex: On a rocket launch, the shuttle exerts a downward force, and tre reaction farce of the Same size pushes it upwards.
