Question20. Keesha designs an experiment to test the effect of force on the motion of a ball. She used a rubber band wrapped around the legs of a chair to launch the ball. She discovers that the farther she pulls back with the rubber band, the faster the ball travels. Which conclusion should she draw? a. Increasing the weight of a moving object will increase its speed. b. Increasing the force applied to a moving object will increase its speed. c. Decreasing the force applied to a moving object will increase its speed. d. Increasing the distance an object travels will increase its speed.

Studdy Solution
Evaluate each conclusion option:
- Option a: "Increasing the weight of a moving object will increase its speed." - This is incorrect because the experiment does not involve changing the weight of the ball.
- Option b: "Increasing the force applied to a moving object will increase its speed." - This is correct because the experiment shows that more force (pulling the rubber band further) results in higher speed.
- Option c: "Decreasing the force applied to a moving object will increase its speed." - This is incorrect as it contradicts the observed relationship.
- Option d: "Increasing the distance an object travels will increase its speed." - This is incorrect because the experiment focuses on force, not distance traveled.
The correct conclusion is:
$$\boxed{\text{b. Increasing the force applied to a moving object will increase its speed.}}$$
