Kinematics in one dimension
Suppose that a car traveling to the East (+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 positive.
A statement cannot be made using the information given.
The acceleration is zero.
The car is decelerating, and its acceleration is negative.
An object is moving with constant non-zero acceleration in the +x axis. The position versus time graph of this object is:
A parabolic curve.
A horizontal straight line.
A straight line making an angle with the time axis.
A vertical straight line.
A brick is dropped from the top of a building. A second brick is thrown straight down from the same building. They are released at the same time. Neglect air resistance. Compare the accelerations of the two bricks.
The first brick accelerates faster.
It is impossible to determine from the information given.
The second brick accelerates faster.
The two bricks accelerate at the same rate.
Under what condition is average velocity equal to the average of the object's initial and final velocity?
This is impossible.
The acceleration must be constant.
The acceleration must be constantly changing.
This can only occur if there is no acceleration.
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.
