2/18 - Copy vocabulary words in NB
1. force - is any
interaction which tends to change the motion of an object. In other words, a
force can cause an object with mass to change its velocity
2. friction - force
that resists the sliding or rolling of one solid object over another.
Frictional forces, such as the traction needed to walk without slipping.
3. drag force - is the resistance force caused by the motion
of a body through a fluid, such as water or air. A drag force acts opposite to
the direction of the oncoming object.
4. gravity - is
the force that causes two particles to pull towards each other. Learn about
gravity and find out how Newton and Einstein explain gravity.
5. net force - is the amount of force that is making the
object change direction or motion.
6. balanced
force - is when two equal forces are applied on an
object pushing both ways. Also they are equal forces acting on an object in
opposite directions.
7.
unbalanced force - when two forces acting on an object are not
equal in size. Unbalanced forces causes can cause.
8. inertia - a
property of matter by which it remains at rest or in uniform motion in the same
straight line unless acted upon by some external forces.
9. velocity - the rate of
change of position along a straight line with respect to time : the
derivative of position with respect to time
10. average speed - It
is distance traveled over time. Speed may vary on a trip, so those numbers are
averaged to come up with average speed.
