This is the meaning of the word "net" in "net force."
What is total?
When comparing a bowling ball and a basketball, this object has more weight (force of gravity).
What is the bowling ball?
If two forces are going in the same direction, this is what you should do to find the net force.
What is add?
This is the name of the property of matter that describes an object's tendency to resist changing its motion.
What is inertia?
Jack and Jill move a pail of water. If Jack pushes with 10 N of force and Jill pulls with 15 N of force in the same direction, this is the net force on the pail.
What is 25 N?
An empty grocery cart and a full grocery cart are pushed with the same amount of force.
This is the cart (empty or full) that will accelerate more.
What is the empty cart?
When a bowling ball and basketball are dropped from the same height at the same time, this is the timing of how they land.
What is they land at the same time?
Jimmy pushes a box with 75 N of force. Friction works against him with a force of 10 N. This is the net force on the box.
What is 65 N?
According to Newton's second law, this is why a small sports car gets better gas mileage than a large SUV.
What is mass resists acceleration? The SUV has more mass, so it takes more force to make it accelerate.
This force explains why a flat paper and crumpled paper fall at DIFFERENT rates.
What is air resistance?
Mrs. Brown and Mr. Slight both throw a football of the same mass. According to Newton's second law, this is why Mr. Slight's football will accelerate more.
What is Mr. Slight has big muscles that can apply more force?
These formulas show Newton's second law written two different ways with capital and lower case letters to compare the acceleration of objects with different masses.
What is a = F / M and a = f/m?
