B. Read the questions carefully and choose the letter of the correct answer.

1. Newton’s second law of motion states that the acceleration of an object as produced by a net force is directly proportional to the force applied and inversely proportional to the mass of the object. Object in uniform circular motion accelerates because of this net force. This acceleration is called ____________.

a. Circular acceleration c. Uniform acceleration

b. Centripetal acceleration d. Constant acceleration

2. In uniform circular motion, as the object moves in circular path, it is said to be accelerating because of a net force. The direction of the acceleration and centripetal force is always _______________.

a. in the same direction c. always changing

b. in opposite direction d. directed outward

3. What happens to the acceleration of object moving in uniform circular motion?

a. Acceleration remains the same.

b. Acceleration constantly changes.

c. Acceleration is in opposite direction as the centripetal force.

d. Acceleration is directed away from the center of the circular path.

4. Where is the direction of the tension force, as a bucket of water is tied to a string and spun in a circle?

a. Perpendicular to the center of the circle

b. Away from the center of the circle

c. Towards the center of the circle

5. In order for Juan to maintain the circular motion of the hammer, he needs to pull the hammer towards him. As a result, the hammer will also pull him. Suppose Juan applied 120 Newton to pull the hammer, how much force will the hammer pull Juan?

 a. The same force as with Juan. c. Less than the force applied by Juan.

b. Greater than the force applied by Juan. d. The net force is zero, since they are both puling toward each other
