Question

27. If Snoopy doubles the force he smacks Lucy what will happen to Lucy's acceleration?
What if he applies triple the force?
28. If snoopy force is constant and he increases his mass by adding charlie Brown to his back what will happen to his acceleration as he moves toward Lucy? If mass double accelerates then_______________

What do arrows represent? ____________________________________________________________
What direction are the arrow supposed to drawn _____________________________________________
Every arrow have a _________________________________ and a __________________________________

Answer 1

27. Use a = F/m (Newton’s 2nd law).
- If Snoopy doubles the force on Lucy, her acceleration doubles.
- If he triples the force, her acceleration triples.

28. If Snoopy’s force is constant and he increases his mass (adds Charlie Brown), his acceleration decreases because a = F/m.
- If the mass doubles, the acceleration is halved.

29.
- What is a Free Body Diagram? A drawing that shows all the forces acting on a single object, represented by arrows.
- How many objects are represented in the FBD? One.
- What do arrows represent? Forces (vector quantities).
- What direction are the arrows supposed to be drawn? In the direction the forces act (usually originating from the object’s center or a dot).
- Every arrow has a magnitude and a direction.
