Unit 5 Section 2 Force: net force and force diagram review

Grade Level:

8

Subject:

Physical Science

Topic:

Combined effects of forces: Unbalanced forces cause an object to change its velocity ( speed up, slow down, change direction).

Objective:

1..Students will be able to look at a free body diagram or an image, determine the direction of the acting forces with 70% accuracy.
2. Students will be able to combine the magnitude and direction of the acting forces on an object to determine the net force with 70% accuracy.
3.Student will be able to identify if the combined forces are balanced or unbalanced, as a result of the net force with 70% accuracy.
4. Students will use their textbook as a resource to reinforce learning.
