Which statement is true?
An object at rest will remain at rest unless an unbalanced force acts on it.
An object in motion always has an unbalanced force acting on it.
An object in motion cannot be acted on by more than one force.
The net force on an object in motion cannot be zero.
Why do you notice the pull of Earth’s gravity but not the pull of the Sun’s gravity?
Gravity only pulls on objects that are touching each other.
Earth is much massive than the Sun.
The Sun is very far away.
The Sun’s gravity only pulls on you during the day.
What changes when unbalanced forces act on an object?
mass
motion
inertia
weight
What force slows a book sliding on a table?
reaction force
inertia
gravity
sliding friction
What does the length of a force vector represent?
the object’s velocity
the force’s magnitude
the force’s direction
the direction of acceleration
What would cause an object to have a smaller acceleration?
Increase the net force on the object.
Decrease the mass of the object, keeping the net force constant.
Increasing the mass of the object, keeping the net force constant.
Decreasing the mass of the object and increasing the net force on the object.
If a student pushes a book across a table with a force of 6 N and the force of friction is 4 N, what is the net force on the book?
0 N
2N
10 N
-2 N
