Force is a vector quantity expressing how bodies act on each other.
Force has a motion and deformation nature.
If you, for example, kick something, you apply force on the given object. Such object may fly

Chapter 6: CIRCULAR MOTION
Circular motion/ rotational motion :
When bodies rotate around something or move in a circular path, its motion is
considered as a circular motion.

This question is about the planet Jupiter and one of the moons that orbits it, called lo.
lo orbits Jupiter at a speed, v of 1.7 x 10 4 m s-1 at an orbital radius, r, of 4.2 x 108m.
a) Show that lo takes approximately 43 hours to o

Introduction of Vector
Physical quantities having magnitude, direction
and obeying laws of vector algebra are called vectors.
Example : Displacement, velocity, acceleration,
momentum, force, impulse, weight, thrust, torque,
Just as a meter is a unit of length and a pound is a unit of weight we introduce the unit
vector (although not a standard quantity per se). Given a three-dimensional coordinate system:
We let i represent the X direction
( -i is the X directio
