C165 1 Questions with CORRECT Answers
Question:
What is NOT a correct statement about inertia?
Answer:
Inertia is the resistance of matter to changes in its motion. An object with less
mass has more inertia. An object with more inertia is more difficult to
accelerate. Inertia is the tendency to keep the same motion. An object with less
mass has more inertia.
Question:
Which derived unit does NOT measure speed?
Answer:
mm/min2 km/hr m/s cm/day mm/min2
Question:
For which case is there a net force acting on the object?
Answer:
A hockey puck sliding across ice at a constant speed in a straight line An apple
that has fallen to the ground A 300 lb weight being held motionless over the head
of a weight lifter A rocket accelerating upward at a rate of 5 m/s2
Question:
Which force statement is FALSE?
Answer:
A force can cause a change in motion. Acceleration is caused by a force. A force
is not needed to cause acceleration. A force is a push or a pull. A force is not
needed to cause acceleration.
Question:
If the net force acting on an object is halved, how will the acceleration change?
Answer:
The acceleration will double. The acceleration will remain the same. The
acceleration will change in an unpredictable way. The acceleration will be half as
much.
