What are some forces in a pendulum?

Question

potential engery, kneitc energy....stuff like that....

plz explain what the forces and energy you name are...

Answer 1

Note energy is very different from forces. If u want forces in a pendulum, they are friction at pivot, tension in string, weight of pendulum, centripetal force due to motion and drag force experience by pendulum(very insignificent).

Answer 2

The pendulum arm experiences ocilliatory moving force in the form of tension as it swings from one gravity energy level to the other.
The motion of the swing is a two vector motion . One is inertial energy the other is gravitational energy.
AS per Newton's fist law of motion the pendulum could swing for ever if it wasnt for energy losses due to friction.
Therefore the swing of the pendulum is damped.

Note ;a force is Energy per unit distance. And a force doesnot move unless Power is given to mass to make it move.
The velocitty of the Pendulum arm swing is equal to the Power appied to the arm divided by the force on the swing.

Answer 3

The energies acting on a pendulum is different then the forces.
The forces are the tension on the string, the weight of the object, the air resistance, the resistance on the pivot, the gravitational force.
The energies are the potential energy, the kinetic energy.

Answer 4

Energy from the pizza you ate enables the pendulum you push that provides kinetic energy in the swing which is then converted to potential energy which is at its greatest at v=0.
Friction and gravity exert forces and for some, psychokinetic energy.

Answer 5

Hey u r question if totally diffrent dan the data .... Force n energy r 2 diff concepts ....

ne ways....


Wen pendulum moves
Wen Pedulum is @ Extreme position KE =0 PE=max

@ Central position PE =0 Ke = Max ....
Look @ D Rough graph i cr8ed ... u willl get a rough idea

Forces acting are ... Gravity .... Normal reaction as the Tension on the string ... the graph can be like this

Answer 6

Restoring force mgsin@ ( where @ is the angle)
Tension by the thread upon the bob.
Weight of the bob mg.

Answer 7

weigh, distance of the first stroke, height off the ground, gravity, the type of material used, i.e. plastic VS Gold.
movement and resistances to movement applied forces in motion.

I have to go to bed now, my mind is getting heavy!

Answer 8

friction at the pivot point?

air friction too

Answer 9

momentum, gravity, friction, wind resistance, possibly tension are a few...

Answer 10

momentum
weight
