6. Glenn is spinning a small block tied to the end of a string, so that the block exhibits uniform circular motion
The path cannot be know without first knowing mass and velocity.
It will follow a curved path, spiraling outward.
It will continue along a path tangent to the circle.
It will follow a path perpendicular to the circle.
Newton's first law states that an object will no accelerate (change speed or direction) unless it is acted upon by an
