Question

5. [lpt Indicate whether the following statements are always true or can be false (Select T-True, F-False. If the first is F and the rest T, enter 1.1.1.11). A) If two objects are under the influence of equal forces, they must have the same acceleration. B) There must be a net force on a car rounding a curve while maintaining a constant speed. C) If a net force acts on an object, the object's velocity will change. D) The net force which acts on an object which remains at rest is zero. E) There is no difference between mass and weight. F) In order not force applied. to slow down, a car moving at a constant velocity needs a small net Submit All Answers

Explanation / Answer

A
If two objects are under the influence of equal forces, they must have the same acceleration ---- False

it would be true if the two objects are of same mass and only the two forces acting on them only .

B

There must be a net force on a car rounding a curve while maintaining a constant speed ---- True

because the centripetal force acts on it , mv^2/r where v is speed of the car  

C

If a net force acts on an object, the object velocity will change. ----True

if the net force acts on the object which is constant then there is constant acceleration means change in vlocity

D
The net force acts on an object, which remains at rest is zero ---- True  

if the net force acting on the object is not zero then the body will move in a direction where the resultant force is acting on the object

E

there is no difference between mass and weight --- False

because mass is constant wehere ever we measuere , but weight W = mg depends on g, we know that g value varies so its False

F
In order not to slow down, a car moving at a constant velocity needs a small net force applied --- False

as the car is moving with constant velocity so acceleration is zero no force needed not to slow down
