How can you increase the magnitude of friction between two surfaces ? How can you decrease the magnitude of friction
1 answer:
The frictional force between two surfaces is given by:
where
is the coefficienct of friction
is the force with which one surface is pushed against the other one
Looking at the formula, we see that there are two possible ways to increase the friction:
1) by increasing the coefficient of friction (for instance, by making the surfaces more "rough"
2) by increasing, the force with which one surface is pushed against the other
Similarly, in order to decrease the friction, the two possible ways are:
1) by reducing the coefficient of friction
2) by reducing the force

Answer : The kinetic energy depends directly on the mass of a particle.
Explanation :
We know that the kinetic energy of any particle is given by :
Where,
m is the mass of an object.
v is the velocity with which it is moving
Kinetic energy is due to the motion of the particle.
So, the kinetic energy of a particle is directly proportional to its mass.
Hence, the conclusion of the question is if the mass of a particle is increases then its kinetic energy also increase.
