5/31 MCQs for:
Kinematics in one dimension
An object is moving with constant non-zero velocity in the +x axis. The velocity versus time graph of this object is:
A parabolic curve.
A straight line making an angle with the time axis.
A vertical straight line.
A horizontal straight line.
When is the average velocity of an object equal to the instantaneous velocity?
Only when the velocity is increasing at a constant rate.
Only when the velocity is constant .
Never.
Always.
When an object is released from rest and falls in the absence of friction, which of the following is true concerning its motion?
None is true.
The speed of the falling object is proportional to its mass.
The speed of the falling object is proportional to its weight.
The speed of the falling object is inversely proportional to its surface area.
Suppose a ball is thrown downward in the absence of air resistance. Make a statement concerning its acceleration.
Its acceleration is zero.
Its acceleration is constantly decreasing.
Its acceleration is constantly increasing.
Its acceleration is constant.
Suppose that a car traveling to the West (-x direction) begins to slow down as it approaches a traffic light. Make a statement concerning its acceleration.
The car is decelerating, and its acceleration is negative.
A statement cannot be made using the information given.
The car is decelerating, and its acceleration is positive.
The acceleration is zero.
