Circular motion

meaning an object in motion stays in motion, with the same speed and direction unless acted upon an unbalanced force.

inertia

Centrifugal (doesn't exist) means outwards or away from center while centripetal means inwards and center seeking.

Explain the difference between a "Centripetal" and "Centrifugal" force.

The velocity is called tangential because the velocity is perpendicular to the circle. So if you let go of the stopper in front it will go to the left, since velocity goes that way. It's the object inertia that keeps it moving and it's tagent to the circle.

Explain what this velocity is called and then explain why the stopper went in that direction.

the radius doesn't change the time would cut in half since speed and time have an inverse relationship

If you were to double the speed of the turntable how would this affect each of the following variables radius of the circle period

The force is centripetal, meaning that it's center seeking. With the stopper, the tension from the string pulls the stopper inward. Since force is coming from the center of the circle, it's pulling the acceleration inward and it accelerates due to the change in direction, always constant.

Then explain why the force was in this direction, what the force is called, and what provided this force What was this acceleration called, and why did it accelerate in the direction you identified.

They have an inverse relationship, since velocity is in the numerator and time in in the denominator, so if velocity increases, time cuts in half and vice versa.

They have a direct relationship, since they are both in the numerator, so if Velocity increases, so will the radius and vice versa.

is the motion of an object in a circular motion with a constant or uniform speed

Uniform circular motion

2 (3.14)r/t,

Vt=

since there is no unbalanced force on the ball, thats way it keeps going forward, The force acting on the ball is ineteria

a ball travels on a circular track of white boards, the ball keeps going forward even though the white boards have curved, what force causes this balls motion, what provides the force, and what is the force called

to will move tangentially to the circle

if you let go off the yo-yo, what will the yo-yo do

90 degrees

the angle between the velocity and acceleration is

friction

what force provides the centripetal force to acerbate the pennies

the tension acting on the yo-yo's string

what provides the centripetal force to keep the yo-yo spinning

B since it needs more force to hang on

which penny has the largest centripetal acceleration

slide of the road in the direction tangent to the curve of the roadway

If the car is entering a curve hits patch of ice it will..

an outward force. This misconception can come from the idea of making a when you're making a left turn in your car your body goes right, outwards.

The common misconception is the notion that objects in circular motion are experiencing

They have a direct relationship, since they are both in the numerator, so if Velocity increases, so will the radius and vice versa

explain what the relationship is between V and r (inverse or direct), and how you know it is this relationship.

the friction acting on the wheels provides the force to keep the car on the road

if a car driving around a curve in the road, what is the centripetal force that keeps the car on the road

low tangential velocity then B, since B has the larger radius

if penny a is closer to the center while penny b is near the edge then penny a has a

time cuts in half, both velocity and acceleration increase

if the speed was increased, what happens to the time, velocity, and acceleration

you keep going in the same direction you were going because of the lose of friction and the interia

if there is ice on the road and the car attempts to go around the circle, but slips off the road, what direction does it go in

yes, since they are going in different directions

if vi goes 5 m/s right and vf goes 5 m/s left is there an acceleration

penny b since its need more force and friction to stay on

if you speed up the record player, which penny would fall off first
