How will the velocity of the book change as it moves across the surface with friction?

The velocity of the book will decrease as it moves across the surface with friction. Friction acts in the opposite direction of motion, slowing down the book.


Is friction the rate of change in velocity?

Acceleration is the rate of change in velocity. It has nothing to do with friction, unless friction is causing the change.


How is friction a force?

Due to friction velocity of a body gets reduced, reduction in velocity causes change in velocity. This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.

Why does velocity of water change with depth?

The velocity of water changes with depth due to variations in pressure and friction. Near the surface, water velocity is typically faster due to less friction, while deeper in the water column, velocity may decrease due to increased pressure from the weight of the water above. This change in velocity with depth is also influenced by factors such as the slope of the river or ocean floor and the density of the water.


Are the friction losses of the machine linear?

Friction losses in a machine are typically non-linear. Friction force is proportional to normal force but can vary with factors like surface roughness, lubrication, temperature, and sliding velocity, causing non-linear behavior. As a result, friction losses may change unpredictably with different operating conditions.


What is that which can cause an object with mass to change its velocity?

A force acting on the object can cause it to change its velocity. The force could be due to interactions such as pushing, pulling, gravity, or friction.


What happens to a ball as it rolls across the floor?

As the ball rolls across the floor, kinetic energy is converted to heat and sound due to friction between the ball and the surface. The ball's speed and direction may change depending on the surface it is rolling on and any obstacles in its path.


How the coefficient of friction between a body and a surface change if the mass of the body is doubled?

The coefficient of friction between a body and a surface does not change if the mass of the body is doubled. The coefficient of friction is a property of the material of the surfaces in contact and their interaction, not the mass of the body.


Can impulse of force zero even force is not 0?

Yes. A non-zero force may not be sufficient to alter the velocity - for example if it is smaller that the limiting friction. No change in velocity implies no change in momentum and so impulse = 0.
