Net Force
When all individual forces acting on an object are balanced, it is the natural tendency of an object to _____. List all that apply in alphabetical order with no spaces between letters.
maintain its state of motion
eventually stop
accelerate
either speed up, slow down or keep the same speed
keep its velocity constant (either at a zero or non-zero value)
Diagram shows a cat chasing a rat.
The inertia of the cat is larger than the rat because
the size of the cat is bigger than the rat.
the mass of the cat is larger than the rat
the length of the cat is more than a rat.
the height of the cat is more than the rat.
Suppose that an astronaut throws a baseball in outer space at a location far from significant influences of gravity and air resistance. One would expect that the baseball would ____.
eventually stop since all objects ultimately "lose their steam"
eventually stop as its inertia slowly becomes used up
continue in motion with the same speed and direction
either a, b, or c -- depending on whether the astronaut continues to push it
How do you know if this object is balanced?
It's unbalanced; it's net Force is 14N
It's balanced; its net Force is 0N
It's unbalanced; it's net Force is 10N to the left and 4N upwards
It's balanced; the object moves to the left
What is the net force?
17N to the left
3N to the right
17N to the right
3N to the left
