Learning Check - Forces December 16, 2022 Learning Goal: Demonstrate an understanding of forces and Newton's laws Success Criteria I can draw from body diagrams I can describe Newton's three laws I can solve problems related to net force and acceleration in 10 1. Draw a system diagram (sketch) and a free body diagram for the bolded object in each of the following situations. No numerical answers are necessary, but the relative magnitudes of the force vectors should be reflected in their lengths. (Le. If 2 forces are equal, they should be represented with arrows that are equal a) A monkey is hanging bj A force is applied horizontally to a c) An ice skater glides from a tree and not book in order to accelerate it across across the ice with moving. a table to the right constant velocity. d) A hot air balloon is e) A baseball is moving through the f) A box being slid up a moving upwards with alr. Neglect air resistance. ramp at constant constant velocity velocity.2. State Newton's Three Laws and cite an example of each from a television show or a movie. Law Example Newton's 1st Law Newton's 2st Law Newton's 3st Law 3. Complete the questions below. 8) bi F = F = m = ? kg m = 15 kg F. = 80 N v= constant F. = m = F.= a = 30 m/s' [up] F = F =The following system has identical material blocks pulled across a horizontal surface by an applied force. Each block Is connected by a string. The coefficient of kinetic between the blocks and the surface Is 0.20. 2.0 kg 12 kg 14 KZ - FACESN aj Draw free body diagrams for each block. bj Determine the friction force between each block and the surface. c) Determine the acceleration of the system
