When moving in a horizontal circular path, what direction is acceleration?

• In the opposite direction of motion

• Tangential to the circle in the direction of motion

How is acceleration seen in circular motion?

• Velocity increases as the object travels in a circle.

• Velocity decreases as the object travels in a circle.

• The object changes direction as it travels in a circle.

• There is no acceleration as an object travels in a circle.
