For a rough surface at a particular angle there will be more friction than if the same material has a smooth surface i am sure their is an exception to this but that is a special case yet f it seems to be fixed for a particular angle.
A ball is being rotated in a rough floor find.
Almost everybody at some point in their lives has bounced a rubber ball against the wall or floor and observed its motion.
Not all balls are equal.
B a physics student stretches a spring.
Mass and elasticity affect how high the ball will bounce and how far it will travel.
These principles will be discussed.
W f d cos since cos 180 then w 0.
For a growing number of men however the erotic art of ball busting is a sought out sexual.
Bouncing ball physics is an interesting subject of analysis demonstrating several interesting dynamics principles related to acceleration momentum and energy.
What makes a ball bouncy.
Then have your lab partner measure the time t 20 1 it takes for the ball to complete 20 revolutions.
A ball s ability to bounce has a lot to do with its elasticity.
Or using the definition of work.
Ensure that the ball is rotating in a horizontal circle before measuring the time.
Have you ever wondered why some balls bounce higher than others.
A 12 n horizontal force is then applied to it.
Interchange roles of whirler and timer and repeat the measurement to obtain time t 20 2.
So what is elasticity.
This does not mean the maths is wrong.
I find it difficult to reconcile my thinking with the maths.
A 40 n crate rests on a rough horizontal floor.
C a projectile falls toward the surface of earth.
D a box is pulled across a rough floor at constant velocity.
Keep the width in your stance too.
This lesson compares the bouncing of a bocce ball a tennis ball and a golf ball.
Even a hard rubber ball won t bounce if you drop it onto the dry part of a sandy beach.
Repeat taking measurements until you get a pair of times that differ by.
Objects that are more stretchy are usually more elastic too.
F or most men getting kicked in the testicles is one of the worst things that could happen to them.
Frictions acts in the opposite direction to the displacement so the work is negative.
A g g.
A box is being pulled across a rough floor at a constant speed.
Wheel having a diameter of 40 m is fitted with a cage and platform on which a man of mass m stands.
A a ball rolls down an inclined plane.
It s an object s ability to return to its original shape after being stretched or squeezed.
So does the friction of the surface on which the ball lands.
E a child pulls a wagon across a rough surface causing it to accelerate.
The wheel is rotated in a vertical plane at suck a speed that the force exerted by the man on the platform is equal to this weight when the cage.
What can you say about the work done by friction.
