Explain why the work done of sliding friction is negative when an object undergoes a dispalcement on a rough surface?
JunaidSaeed
Work is done when a force is applied over a distance. If the force acts opposite the direction of motion, like friction, then the work is negative.

Explain the term dynamic limiting friction and rolling friction?
awesome looking
What are the two main factors on which friction depends?
roughness of surface explain.... please..
State and explain with examples that friction can help the cause of motion in certain situation?
friction is the force that slows things down or prevent things from moving
Explain how friction affects the motion of an object?
Friction is speed's worst enemy. If no forces act on an object, it is stationary. If a force acts on an object, it keeps going forever until another force acts on it (such as friction!!!).
In order for work to be done explain the two things that must occur?
A force must act on a body which, as a result undergoes motion in the direction of the force.

Explain how friction is involved in energy transformation?
Friction creates heat - heat travels by convection, conduction or radiation.
Explain would the formation of a goiter be positive or negative feedback?
Negative.
Does the movement of woodpecker involve friction force explain?
Every movement you make requires friction. When you walk, it requires friction. When a woodpecker is pecking a hole in a tree, it requires friction for him to keep his toes in the tree- static friction, to be specific. Hope that helped!
Jack is going skiing does he need high or low friction between his skis and the snow?
low friction
Can pv r be negative Explain?
no pressure and volume can never be negative quantities
How does physics relate to friction?
physics explain what needs to exist or happen to cause friction and so provide ways to measure (control) frictions.

Explain how wood burning in a fire place undergoes a chemical change?
Burning is an oxydation reaction so a chemical change.
Explain how frictional force is used to reduce the speed of a moving object?
Friction is a force that always acts in a direction opposite to that of motion. So the frictional force does negative work on the velocity of an object ( thus reducing the speed of an object).
How would you explain the childrens what is negative 3 plus5?
Explain that the negative(-3) can be moved and become a subtraction sign. -3+5=5-3
Will a negative number to the fifth power be a positive or a negative value explain?
Negative, because 5 is an odd number
