Question 198: Work, Energy and Power & Circular Motion

Question

A particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle, the motion of the particles takes place in a plane. It follows that

Accepted Answer

Work done by such force is always zero when a force of constant magnitude always at right angle to the velocity of a particle when the motion of the particle takes place in a plane.
$$	herefore$$ From work-energy theorem, $$  \Delta K = 0$$
$$	herefore$$ $$K$$ remains constant.

Answer

its kinetic energy is constant

Answer

is acceleration is constant

Answer

its velocity is constant

Answer

it moves in a straight line

Work, Energy and Power & Circular Motion
