(2) Where is vi (as a vector) in relation to circle and radius? (3) If ac = 2.0 m/2 and the radius i 3.5 m . Calculate the Tangential Velocity. (4) What is the difference between ac and (at)? (5) Why is there (at) even if the vt is constant? (6) What is the centripetal force?

Centripetal means moving or tending to move toward the center. Centripetal acceleration is the rate of change of tangential velocity. 
2. Vector is tangent to the circle and it is thus perpendicular to the radius. 
3. Tangential velocity is 7 because 3.5 x 2=7.0. 
4. The difference between centripetal acceleration and tangential acceleration is that tangential acceleration is the direction that is perpendicular to the circle. It is also a measure of how the tangential velocity of a point at a certain radius changes with time. Centripetal acceleration is the rate of change of tangential velocity. 
5. at is the perpendicular direction and the speed (vt) does not influence it. Also at changes but vt remains constant so there is no correlation.  
6. Centripetal force is a force moving in a circular path towards the center.
7. Centripetal force is mass times velocity squared divided by radius. Mass is the weight of the object and thus greater the object's mass the smaller the centripetal force. Velocity involves the speed of the object and the greater the velocity the closer it moves towards the center. It's easier for the object to move towards the center when there's a smaller radius.

2. Vi(as a vector) is tangent to the circle and perpendicular to the radius. 
3. Tangential velocity is solved with the equation v=w(angular velocity)*radius. So (3.5m)(2m/s)= 7m/s. 
4. Tangential velocity is the velocity that is tangential to the circular movement and it changes at the direction changes. It does not keep the object moving thereas the centripetal acceleration makes sure the object continues to move in a circle. 
5. Tangential acceleration changes because the direction of movement constantly changes. However tangential velocity remains constant. Having said that, tangential acceleration exists to keep the object from falling out of the air or ceasing the circular movement. 
6. Centripetal force is the movement that keeps object moving in a circle and is directed towards the middle of that circle. 
7. Centripetal force =(m)velocity^2/ radius. Centripetal force is a net force and the movement will be the direction of the extra force. Velocity is squared then divided by the distance from the center to the edge of the circle. That represents a distance which is then multiplied by the mass. The bigger the mass, the less centripetal force is required. ]]> 2016-11-14 23:09:00 UTC https://padlet.com/tec430/qz2llszxw3ju/wish/137578222 Chisondi https://padlet.com/tec430/qz2llszxw3ju/wish/137578560 1.)

    5) Tangential acceleration is there although vt is constant, it doesnt have an affect through velocity. It is centripetal acceleration 
    6) Centripetal force is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving 
    7)Centripetal acceleration is the tangential velocity You have to multiply by 2 then divided by the radius
