What is the centripetal force that allows a car to turn?
friction
What is difference between centripetal force and centrifugal force?
Centripetal force is defined as, “the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation,” while centrifugal force is defined as “the apparent force that is felt by an object moving in a curved path that acts outwardly away from the center of …
Why do we feel centrifugal force?
When you are standing upright imagine a downward external force on your head and an equal magnitude upward force on your feet. These two forces will compress you and you “feel” being compressed as a result of these two forces acting on you.
Who discovered centrifugal force?
Newton
What is the meaning of centripetal?
1 : proceeding or acting in a direction toward a center or axis centripetal acceleration of a body. 2 : afferent centripetal nerves. 3 : tending toward centralization : unifying centripetal factors that hold the parts together.
Where is centrifugal force greatest on earth?
the equator
What can you say about the direction of the net force and acceleration?
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. The above equation is often rearranged to a more familiar form as shown below.
What is the difference between centripetal acceleration and centripetal force?
The centripetal acceleration is the acceleration a body experiences in centripetal motion (moving in a circle or along an arc). On the other hand, the centrifugal force is a fictitious (imaginary) force the object experiences during circular motion.
What is another name for centripetal acceleration?
The force which causes the acceleration is directed towards the center of the circle and is called a centripetal force.
What does centripetal force depend on?
Three factors which affect the centripetal force are: mass of the object; its speed; the radius of the circle.
Does mass affect tangential acceleration?
1 Answer. Angular acceleration is inversely proportional to mass.
What if tangential acceleration is constant?
In the case of the uniform circular motion, the speed (v) of the particle in uniform circular motion is constant (by definition). This implies that tangential acceleration, aT, is zero. Consequently, angular acceleration ( aTr ) is also zero.
What is the difference between tangential and radial acceleration?
This centripetal acceleration is directed along a radius so it may also be called the radial acceleration ar. If the speed is not constant, then there is also a tangential acceleration at. The tangential acceleration is, indeed, tangent to the path of the particle’s motion.
