Question

Case I.) You hold a brick at rest in your hand. a.) How many forces act on the brick? (Make sure you can name them.) --Select- -Select- b.) Are these forces: opposite in direction? -Select- equal in size? -Select- an action-reaction pair? -Select- yes no Case II.) You now accelerate the brick directly upwards. a.) How many forces act on the brick now? (Neglect air resistance. Make sure you can name them.) -Select- -Select- b.) Are these forces: opposite in direction? -Select- equal in size? -Select- an action-reaction pair? ---Select- yes no Final summary: What is the action-reaction pair of the force of gravity acting on the brick? ---Select- and which way does it point? --Select- What is the action-reaction pair of the normal force acting on the brick? --Select- and which way does it point? --Select- ---Select- the force on the brick from the hand Submit Answer the force on the hand from the brick the force on the Earth from the brick the normal force on the brick the weight of the brick

Answer 1

Case I Block Hand a) act on the block one is gravitational force song and other one is Normal ug reaction given by hands are opposite in direction equal in fize? yes an action – reaction pair yer.

Answer 2

The answer above is correct except for the last part, they are NOT an action-reaction pair.
