Newtons laws of motion
What is newtons 1st law known as the law of
Inertia
what is force
a push or pull on an object
what is friction
a force that acts when two surfaces touch each other.
acceleration is
the rate of change in the speed of an object.
what tells us the rate at which an object moves
speed
objects stay at rest unless
unless acted on by an unbalanced force.
what does force have
size and direction
if you kick a ball, it will roll to a stop because
friction slows the ball down
when at rest, acceleration will be at
0
A change in position measured by distance and time is
motion
what causes an object to slow down or speed up.
friction
how is force measured
in Newtons (N)
less friction means
its harder to stop.
is there acceleration while you are at a constant speed?
no
what tells the speed and direction of a moving object
velocity
which law states force is dependent on the mass and acceleration of an object.
3rd law
what is the sum of forces acting on an object
Net forces
Friction only happens with
solid objects
what is the opposite of acceleration?
deceleration
where an object stops is
origin
F=ma
2nd law
what shows direction and strength of force
arrows
Friction is harder to have with
liquids like rain and ice
If time is increasing to the right but its distance does not change, it is
at rest
the exact place an object is
position
