October 27th, 2014 Net Force Worksheet
For each force that pulls or pushes to the left you must put a negative sign in front of it. Remember that Force is a vector and direction matters. Draw vectors for each picture!
1. b. Add the two forces to get the Net force (6 N)
c. Divide the Net Force from (b) by the mass to get the acceleration. (3)
2. b. Add the two forces to get the Net force (1500 N)
c. Divide the Net Force from (b) by the mass to get the acceleration. (3)
3. b. Add the two forces to get the Net force (8 N)
c. Divide the Net Force from (b) by the mass to get the acceleration. (2)
4. This time the "tug of war" isn't between two people but between one person and the Force of Friction. b. Add the two forces to get the Net force (4800 N)
c. Divide the Net Force from (b) by the mass to get the acceleration. (6)
October 24th, 2014 Newton's 2nd Law GUESS worksheet
Refer to the example at the top. All of these problems have to do with using Newton's Second Law (F=ma) to determine weight and mass. If you have any objects mass (in kg) then multiply it by the acceleration due to gravity (g=-10m/s^2) to calculate the Force of gravity (the weight in Newtons). If you are given the weight in Newtons then divide it by the acceleration due to gravity (g=-10m/s^2) to calculate the mass (in kg).
11. a. This is a Net Force problem. Draw all four forces going the correct direction.
b. Remember that the Net Force is the sum of all the forces in the problem. Add up all four of the forces; don't forget to make any force to the left negative. The sum of the forces should be to the left (-5 N).
c. Use Newton's 2nd Law (F=ma) to calculate the acceleration that a 2 kg mass would feel when 5 N are applied. (2.5 m/s^2)
