the inner product of two vector quantity is certainly a scalar quantity..LanguageNerd said:But how can it be a scalar quantity when it contains a vector quantity?
What do you mean by this? The radius of circular rotation is changing?Philip Wood said:and the particular radius keeps changing!
Think of the radius as a vector from the center to a particular point on the circle. It changes as you move around the circle.adjacent said:What do you mean by this? The radius of circular rotation is changing?
Oh. I thought he said that the radius(Length) is changing :shy:Doc Al said:Think of the radius as a vector from the center to a particular point on the circle. It changes as you move around the circle.
At any point, the radial acceleration points toward the center of the circle (opposite to the radius vector at that point). That direction changes as you move around the circle.
:rofl:Philip Wood said:He ought to have been clearer!
The KE constant in circular motion refers to the kinetic energy that remains constant throughout the motion of an object in a circular path. It is also known as the conservation of energy principle.
The KE constant in circular motion can be calculated using the formula KE = 1/2 * m * v2, where m is the mass of the object and v is its velocity. This formula represents the relationship between an object's mass, velocity, and kinetic energy.
The KE constant is important in circular motion because it helps us understand the energy conservation principle. It shows that although the speed and direction of an object may change in circular motion, its kinetic energy will remain constant as long as no external forces act on it.
The KE constant plays a crucial role in the motion of an object in a circular path. As the object moves in the circular path, its speed and direction change, but its kinetic energy remains constant. This means that the object will continue to move at a constant speed unless an external force acts on it.
No, the KE constant cannot change during circular motion as long as there are no external forces acting on the object. This is because of the conservation of energy principle, which states that energy cannot be created or destroyed, only transferred or transformed.
