Answer:
Explained below
Explanation:
For the geometric meaning, I've attached a parallelogram showing two vectors a and B and also the angle between them as θ.
We can see that the two vectors are adjacent to each other.
So the magnitude of the product of the two vectors is simply the area of the parallelogram which is base x height. Thus;
Magnitude = |a| sin θ × |b|
This can be rewritten as;
|a|•|b| sin θ
Answer:
Centripetal force is the force that is necessary to keep an object moving in a curved path and that is directed inward towards the center of rotation.
Explanation:
Definition of centripetal force:
Centripetal force is the force that is necessary to keep an object moving in a curved path and that is directed inward towards the center of rotation.
Example of centripetal force
A string on the end of which a stone is whirled about exerts a centripetal force on the stone.
The diagram is shown below
Where
The centripetal forces acting towards the centre C that is
and the direction is from A to C.
And the stone is moving in a circular motion with center as C.
