Uniform Circular Motion unit of high school physics
The object experiences a force, which has a component directed ___.
towards the center of the circle
___ causes objects to move in a circle.
Centripetal force
There can be a force pushing outwards as long as the net force is ___.
inwards
In UCM, even though the speed is constant, acceleration is ___.
not zero
In UCM, why can an object have a velocity that can be constant, but still have acceleration?
As the object is in UCM, the magnitude of the velocity will be the same, but the direction of the object’s motion is always changing. Due to the changing direction of the object’s motion, acceleration is not zero.
The acceleration and the net force vector are directed ___.
inward
If the net force upon the object is suddenly reduced to zero, the the object would ___.
suddenly depart from its circular path and travel tangent to the circle
What force causes this object to travel in a circular path?
An eraser is tied to a string swung in a horizontal circle.
Tension force
What force causes this object to travel in a circular path?
The moon orbits the earth.
Gravitational force
What force causes this object to travel in a circular path?
A car makes a sharp right-hand turn along a level roadway.
Friction
What force causes this object to travel in a circular path?
A roller coaster car passes through a loop. Consider the car at the bottom of the loop.
