QUESTIONS AND ANSWERS
◉ What is the difference between constant, instantaneous, and
average speed.
Answer: · constant speed is where the speed is the same throughout
and instantaneous speed is speed given at any moment and average
speed is a total distance traveled divided by the amount of time it
took to travel it.
◉ Newtons Laws.
Answer: Newton's first law states that every object will remain at
rest or in uniform motion in a straight line unless compelled to
change its state by the action of an external force. The second law
states that the acceleration of an object is dependent upon two
variables - the net force acting upon the object and the mass of the
object.
The third law states that for every action (force) in nature there is an
equal and opposite reaction.
◉ Coefficient of friction.
Answer: · A coefficient of friction is a value that shows the
relationship between two objects and the normal reaction between
, the objects that are involved. ... The coefficient of friction depends on
the objects that are causing friction. The value is usually between 0
and 1 but can be greater than 1.
◉ Torque.
Answer: Torque is a measure of the force that can cause an object to
rotate about an axis. Just as force is what causes an object to
accelerate in linear kinematics, torque is what causes an object to
acquire angular acceleration. Torque is a vector quantity
◉ Mechanical advantage.
Answer: · Mechanical advantage is the ratio of the force produced by
a machine to the force applied to it, used in assessing the
performance of a machine.
◉ Input vs output force.
Answer: · The difference between the two is very simple to
understand: Input Force represents the amount of force that you put
into another object. Output Force represents the force that a specific
object has as a result of the input force.
◉ Gravitational force.
Answer: · The gravitational force is a force that attracts any two
objects with mass. ... In fact, every object, including you, is pulling on
