Packet #1
1. Motion and Forces
Broad Concept: Newton’s laws of motion and gravitation describe and predict the motion of
most objects.
21.) The forces acting on a skateboarder
22.) Two forces act on the 2 kg box shown
moving at a constant velocity along a sidewalk
below.
are shown in the figure below.
A 4 N force acts to the right and a 6 N force
acts to the left. What is the net force acting on
the box?
A. 10 N to the right
B. 10 N to the left
C. 2 N to the right
Which of the following is the net force on the
D. 2 N to the left
skateboarder?
A. 0 N
B. 70 N
C. 670 N
D. 1270 N
My Answer and Explanation:
My Answer and Explanation:
A. All of the force on the skateboarder
D. To find the net force you must
are balanced. The 35N right balances
subtract since the two forces are acting
the 35N left and the 600N up balances
in opposite directions. 6N-4N = 2N. 6N
the 600N down.
(the bigger force) is to the left so the
net force is to the left.
