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?

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.

400

is the length of the path between two points.

What is distance

400
This is a real life example of Newton's first law.
Many right thoughts here! Examples: Seat belt, moving forward in a car, athlete who has trouble stopping suddenly, a golf ball not moving just because you yelled at it, etc.

This force explains why a flat paper and crumpled paper fall at different rates.

What is air resistance?

500
When an object falls, eventually it reaches a point where the downward force is equal to the upward, drag force. This term describes this moment where the net force is zero.
What is terminal velocity?

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?

500

What is acceleration?

What is a change in velocity

500
Some people say that Newton's first law is really just Newton's second law describing a situation in which the acceleration is this amount because the force is this amount.
What is zero?
