In the absence of an external force, a moving object will
move with constant velocity in a straight line
Suppose that an object travels from one point in space to another. Make a comparison
between the displacement and the distance traveled.
The displacement is either less than or equal to the distance traveled.
A projectile is launched with velocity v at an angle θ above the horizontal. The range of the
projectile does not depend upon the acceleration due to gravity at that location.
false
Suppose that an object is moving with constant acceleration. Which of the following is an
accurate statement concerning its motion?
In equal times its velocity changes by equal amounts.
The acceleration of an object does not have to be in the same direction as the net force applied
to it.
false
A net force exerted on an object opposite to the object's direction of motion decreases it speed
and its kinetic energy.
true
The motion of a particle is described in the velocity vs. time graph shown in Fig. 2-2. We can say
that its speed v
decreases and then increases.
A packing crate slides down an inclined ramp at constant velocity. Thus we can deduce that
a frictional force is acting on it
