When an object is not moving, physicists say it is ____________.
What is "at rest".
When you push a book across a table, you are providing this force.
What is applied.
The term used to describe the overall force acting on an object.
What is net force.
The definition of force.
What is a push or a pull.
The force that always opposes motion.
What is friction.
The force responsible for slowing down a skydiver.
What is air resistance or fluid friction or lift.
This is what a bigger arrow in a free body diagram means.
What is a stronger force (greater magnitude).
The unit of force and its abbreviation.
What is Newtons (N).
What is balanced.
The support force that counteracts gravity.
What is normal force.
The net force in a tug of war if someone is pulling left with 1500 N and someone is pulling right with 1400 N.
What is 100 N left.
The support force that one solid object puts on another solid object to oppose gravity.
What is normal force.
A change in motion of an object will only occur if the forces acting on it are ________________.
What is unbalanced.
These are the four major types of friction.
What is sliding, rolling, fluid, and static.
Draw a free body diagram for a water bottle sitting on a table.
What is normal force up and gravity down.
This attractive force pulls objects together due to their masses.
What is gravity (gravitational force).
These are the five ways forces can impact the motion of an object
What are: start moving, change directions, speed up, slow down, or stop moving.
These two factors determine the strength of gravitational force between two objects.
What is mass and the distance between the objects.
Draw a free body diagram of a paper airplane coasting through the air to the right.
What is gravity down, lift (air resistance) up, and drag (air resistance) left.
The type of friction that must be overcome in order to first get an object moving.
What is static friction.
