_______ quantity is a value or measurement that has magnitude, or size, only.
_____ are examples of scalar quantities
mass, time, distance
velocity, time, distance
energy, work, force
torque, mass, time
If the forces are balanced, they will cause a change in the object’s velocity
changes in velocity may occur as changes in the magnitude, direction, or both.
A change in an object’s velocity
A change in the distance
when the velocity is constant
If a forece acts on the object in a direction parallel to the velocity,
the velocity´s magnitude changes
the acceleration magnitude changes
the velocity´s magnitude does not change
