- my best friend shouldn’t die because if she does then who is going to make me laugh? There would be nobody to laugh at my bad jokes and there won’t be nobody there for me when I need it the most. My best friend is needed in this world with out them I would be lost.
Answer:
(1) Support
(2) Tension
(3) Reaction
The constraint forces are forces that occur in pairs such that the net force (effect) is zero
The details of the constraint forces are;
(1) The support force at the top of the swing acting upwards
(2) The tension in the swing rope acting upwards
(3) The (normal) reaction between the legs of the swing frame and the ground
Explanation:
The normal reaction is the force equal in magnitude and opposite in direction to the total weight force the swing and the person on the swing posses due to gravitational attraction which prevents the downward or sideways motion of the entire swing
True because friction happens when two things are rubbed against each other and it creates force and sliding something vigorously against something else can create force.
It's about 6 minutes, as I seem to recall. Sort of the time for the earth to go into shadow darkness when there's an eclipse ???
