1 if you are standing on a bus and the drivor slams
on the brake you will fall_
3 unit for force
4 the net force on an object when 2 forces of 15 n
both push in the same direction.
10 the net force on an object when it is pushed with
50n to the right and 40n to the left.
12 this has the unit "m/s^2"
15 when you sit in the back seat of a moving car and
the drivor turns to the right very hard, your body
will move to what part of the car?
16 what is the acceleration of a ball that is hit with
45n and accelerates 9m/s^2?
17 the force when the acceleration is eleven and the
mass is 2kg
18 the force that is exerted perpendicular to a
surface in contact.
1 what is "g" on a plaent where a 100 kg person
weighs 4500n
2 the tendency of objects to resist changes in
motion, related to mass
5 newton's 1st law says that an object at will
remain at rest, and objects in motion will continue
with constant velocity
6 force = mass x
7 the weight of a 10kg box on earth
8 this never changes when you go to a different
planet
9 unit for mass
11 f1+f2 +f3 = (2 words)
13 mg=
14 what is the net force on a wall that is pushed but
does not move anywhere?
