SPH4U- UNIT 2 TEST
PART A: MULTIPLE CHOICE
1 A force of 1.0 N is equivalent to 1.0 kg m/s2 ( Answer is d)
2 The force in the hand that will throw the ball and the reaction force that is the gravitational force. (Answer is a)
3 The third law of Newton states that for every action, there exist a reaction that is opposite and equal to the action. (Answer is c)
4 To achieve constant velocity of an object, the Newton’s second law says that applying force on an object, it will have an acceleration (F=ma). Hence an object, moving at constant velocity, must have a net force acting on it (Answer is a)
5 Net force is proportional to the variation of velocity. F = m dv/dt. Then acceleration is always in the direction of the net force (Answer is a)
6 Considering that the positive sign represents towards the West and the negative sign represents towards the East , then
F = +13.5 N -21.2 N -33 N +25.3 N
F = +38.8 N -54.2 N
F = -15.4 N
This means 15.4 N towards East (Answer is b)
7 F = ma
Let the unknown force be x
(-20 N-10 N+ x N) = 5.0 kg X 8.0 m/s2
- 30 + x = 40
x = 40 + 30
x = 70 N (Answer is d)
8 F = ma
a = F/m
a = 58.0 N (W)/ 0.45 kg
a = 129 m/s2 (W) (Answer is c)
9 The third law of Newton states that for every action, there exist a reaction that is opposite and equal to the action. the force of the child pulling up on the Earth (Answer is b)
10 F = ma
a = F/m
a = 36 N / (20 + 4) kg
a = 36/ 24
a = 1.5 m/s2
36 N – x N = 20 kg x 1.5 m/s2
36 – x = 30
X = 6.0 N (Answer is b)
