if you kick a bowling ball and then a tennis ball with the same amount of force, according to newtons second law of motion, what will happen? A. the tennis ball will travel farther that the bowling ball B.the bowling ball will travel farther than the tennis ball C. the bowling ball will travel faster but cover a shorter distance D. the balls will travel the same distance
A.the tennis ball will travel farther than the bowling ball
200
what is a force?
push or pull on an object

what is newtons second law?
the heavier the mass the more force needed for acceleration
200
what is the equation for acceleration?
(final velocity-initial velocity)/ time
200
what is the definition of inertia?
an object remains stable and unchanged due to a balanced force

what is friction?
a force that opposes motion between two surfaces that are in contact
300
what is newtons third law?
For every action, there is an equal and opposite reaction
300
what is the equation for force?
mass x acceleration
300
what is the definition of kinetic energy?

how would a man moving a small box compare to a man moving a heavy crate in newtons laws? which law?
the man carrying the heavier box would need to apply more force in order to create acceleration as to the man carrying the smaller box would need to use less force. newtons second law (analyze wording)
