Question

a) Tubby is in an accelerating (non-inertial) reference frame, and sees an object that is stationary relative to him. What conclusion can he draw about the net force acting on the object?

The net force on the object is not zero in Tubby's frame, but there is an inertial frame in which the net force is zero

1.The net force on the object may be zero.

2.The net force on the object must be zero

3.The net force on the object is zero in Tubby's frame, but there is an inertial frame in which the net force is not zero

4.The net force on the object cannot be zero

5.Nothing can be concluded about the net force on the object.

b) Tonga is in an inertial reference frame. If two forces of equal magnitude act on an object, what will she see?



1.The object may be accelerating or moving at constant speed, but cannot be stationary

2.The object may be moving at constant speed, but cannot be stationary or accelerating

3.The object may be accelerating or may be stationary, but cannot be moving at constant speed

4.The object may be accelerating, but cannot be moving at constant speed or stationary

5.The object may be accelerating, may be moving at constant speed, and may be stationary

6.The object may be moving at constant speed and may be stationary, but cannot be accelerating

Explanation / Answer

a)3.The net force on the object is zero in Tubby's frame, but there is an inertial frame in which the net force is not zero b)5.The object may be accelerating, may be moving at constant speed, and may be stationary
