Question
Indicate whether the following statements are always true or can befalse.(Select T-True, F-False. If the first is F and the rest T,enter
FTTTTT).
A) During the collision of a car with a large truck, the truckexerts an equal size force on the car as the car exerts on thetruck.
B) The net force which acts on an object which maintains a constantvelocity is zero.
C) If an object's speed does not change, no net force is acting onthe object.
D) If two objects are under the influence of equal forces, theyhave the same acceleration.
E) In order not to slow down, a motorcycle moving at a constantvelocity needs a small net force applied.
F) An object's velocity will change if a non-zero net force acts onthe object.
Explanation / Answer
A) During the collision of a car with a large truck, the truckexerts an equal size force on the car as the car exerts on thetruck. True , From Newton's third law B) The net force which acts on an object which maintains a constantvelocity is zero. True , as if net force is not zero than it's velocity willchange C) If an object's speed does not change, no net force is acting onthe object. False , In circular motion speed doesn't change but still net forceis not zero . D) If two objects are under the influence of equal forces, theyhave the same acceleration. False , Acceleration =Force/ mass If masses are not equal than acceleration will not be equal . E) In order not to slow down, a motorcycle moving at a constantvelocity needs a small net force applied. For moving in constant velocity , force should be zero . SoFalse F) An object's velocity will change if a non-zero net force acts onthe object. True , So final result is TTFFFT
