An object is being subjected to a
single external force. Which of the following MUST be true?
A. The object remains at
rest B.
The object’s speed will
increase
C. The objects speed will remain
constant D.
The object’s speed will decrease
Homework Answers
Solution) When an object is subjected to a single external force , the objects speed will increase . This is because from Newtons First Law , a body remains in state of rest untill an external force acts on it .
The force cause momentum . So the object moves .
Therefore the objects speed will increase .
Option (B)

What happens to the motion of an object under the influence of a single constant force as you decrease the object’s mass? A) the magnitude of the acceleration would increase B) the magnitude of the velocity would increase but the acceleration would remain the same C) the magnitude of the acceleration would decrease D) the magnitude of the velocity involved would decrease but the acceleration would remain the same

i) _________ True or False. A force with a strength of 50 Newtons acts on two different objects: a car and a truck. Because the force on the truck is the same as the force on the car, both vehicles will experience the same acceleration. Explain your reasoning. ii) Give an example of rotational motion. iii) When the net torque on an object is zero, the object will a) continue to spin in the same direction (clockwise or counterclockwise) b)...
