10 Questions
What will happen to the motion of a luggage cart if the net force on it is 0 N?
The cart will stay still
What happens to the motion of an object when an unbalanced force acts on it?
The object will accelerate
If you push a moving luggage cart forward with a force equal to the force of friction pushing backward, what will happen to the cart's motion?
The cart will continue moving at a constant velocity
If you pull back on a moving luggage cart, how will the net force on the cart affect its motion?
The cart will decelerate
What is the second part of the first law of motion?
An object in motion will stay in motion with a constant velocity if the forces on it are balanced
What happens to an object at rest when the forces acting on it are balanced?
It remains at rest
Which of the following statements best describes balanced forces?
Forces that have a net force equal to zero
What happens to an object in motion when the forces acting on it are balanced?
It moves with a constant velocity
Which of the following is true about unbalanced forces?
They cause an object to change its state of motion
What does Newton's first law of motion describe?
The behavior of an object when acted upon by balanced forces
Test your understanding of how net force and Newton's first law of motion can predict the motion of objects. Learn how to determine if forces are balanced or unbalanced, and how they affect an object's velocity.
