Suppose an object is moving through space in a straight line. What could cause the object to start moving in a circle?
A.
a secondary force that pushes the object away from a center point
B.
an increase in the object's inertia due to friction
C.
a secondary force that pulls the object toward a center point
D.
an increase in the object's mass, which causes the object to slow down

Multiply or divide to make this english distance conversion. 174 inches = feet (14.5, 58, 2,088, 23)
