A hockey puck slides along an icy pond. Without any kind none at all
of friction, the force to sustain sliding is
, What is the net force on a box of chocolates when 4N
pushed across a table with horizontal force of 10N while
friction between it and the surface is 6N?
The sum of the forces that act on any object moving at zero
constant velocity is
The equilibrium rule F=0 applies to Objects/systems at rest
Objects/systems in uniform motion in a straight line
A man weighing 800N stands at rest on two bathroom 300N
scales so that one scale shows a reading of 500N. The
reading on the other scale is
If you leap straight inside a high speed train while it gains Slightly behind your original position
speed, you land
A mosquito flying at 2 m/s encounters a 2 m/s breeze 0 m/s
blwoing in the oppositie direction, giving it a resulting
speed over the ground of
Neglecting air resistance, when you toss a ball upward, 10 m/s
by about how much does its upward speed decrease
each second?
During each second of free fall, the speed of a dropped Increases by the same amount
object
