1st Law
what is the other name of newtons 1st law is known as
law of inertia
The law refers to the net force, which is the sum of all forces acting on an
object
if 1 object experts a force on a 2nd object, the 2nd object experts a force of the same magnitude back on the first object, but in the opposite
reaction
if a cannon shoots a connon ball and its pushed back what law is this
3rd law
whats the formula for acceleration
a = Δv/Δt
if a car is at rest and something hits it is what
a external force
A stronger net force will produce a greater acceleration, causing a faster change in
velocity
forces always occur in pairs, acting on different
what is objects
what is the formula of the first law
ΔU = Q - W
what is acceleration
the rate at which the velocity of an object changes over time.
that an object at rest will remain at rest, and an object in motion will stay in motion with the same speed and in the same direction, unless acted upon by a net
external force
if the net fore on an object is 0 what is its acceleration
zer0
for every action, there is an equal and opposite
what is reaction
what is the formula for newtons third law
F₁ = -F₂ or F_AB = -F_BA
is acceleration and velocity the same?
what is no or just no
A stationary object will stay stationary unless a force causes it to what
move
what is the formula for newtons 2nd law
F = ma
3rd law is often called the law of action and
what is reaction
if a rocket goes to the moon what law is this
3rd law
is acceleration the same as speed
what is no
An object moving at a constant speed in a straight line will continue to do so until a force changes its
speed or direction
If you increase the net force, the acceleration increases proportionally. For instance, pushing a shopping cart harder will make i
accelerate faster.
newtons third law states that for every action there is there is an equal and
opposite reaction
pushing a car versus a truck, where the lighter car accelerates more for the same force
2nd law
is f=m a accelerations formula?
what is no
