verry important question?

Question

a particle is acted upon by a force of constant magnatude which is always perpendicular to the velocity of the particle.the motion of the particle is in a plane.it follows that [1]velocity is constant[2]accelaration is constant[3]kinetic energy is constant

Answer 1

1] velocity is constant

Make certain you understand why - applied physics will come in handy throughout your life.

Answer 2

All three statements are true:

1) Since the acceleration is always normal to the velocity, the tangential component of acceleration is always 0, which means that the tangential velocity is constant.

2) Since F is constant and F = ma, acceleration is also constant.

3) Since velocity is constant, K = 1/2 mv^2 is also constant.

Answer 3

Sorry I dont know u don't understand it or ihaven't understood the thing
Firstly if velocity is a constant then the acceleration produced would be zero
cause acceleration=rate of change of velocity

Answer 4

Energy is defined as the ability to do work. When the work is actually being done, we term the energy "kinetic." When the work is waiting to be done, when there is the potential for work to be performed, we term the energy "potential." Kinetic energy is the energy of motion, potential energy comes from work having been done on an object which was then stored. For example, a rubber band zinged from your finger has kinetic energy. While it was stretched, waiting for you to release it, it had potential energy. The rubber band was stationary, but work had been done on it to move it to its present position.

Answer 5

3 is true if there is no other force acting upon the particle - but I am guessing since I am not a scientist or mathematician. But please check out my sources.

Answer 6

anyway , wat is the question here? firstly, when velocity is constant, acceleration is constant. and so if velocity is constant kinetic energy is constant.
