Types of Forces
A push or pull applied to an object
Applied Force
Objects at rest will...
Stay at rest
The first step in solving for a problem in this class is that you need to...
Identify what you are given and what you are looking for
For every action, there is an __________ and ___________ reaction force
equal and opposite
Unit for distance
m
An attractive force between two objects that have mass
Force of Gravity
Objects in motion will...
Stay in motion
How do you select which equation to use for solving a problem in this class?
Name the type of force that is a 3rd Law example that we measured using the triple beam balances.
Normal Force
Unit for force
N
A force that goes against the motion of two objects that are touching
Force of Friction
What is the vocab word that describes the tendency of objects to maintain a constant velocity?
Inertia
If you have mass and force, which equation do you use to find acceleration?
How does the force of gravity from the sun compare to the force of gravity from the moon?
They are equal and opposite
Unit for mass
kg
A force that pulls inward when a solid object like rope is stretched
Tension Force
You hold up a pen in the air and let go. The pen's inertia is its tendency to...
Stay where it is
If you have mass and acceleration, what equation do you use to find force?
Even if the forces are equal and opposite, why don't they affect things the same?
Mass changes how a force acts on objects.
What is the net force of an object that isn't moving?
0
A supporting force that pushes up on an object against gravity and keeps it from falling through what it is resting on
Normal Force
An object is moving in a straight line and is slowing down. Describe the net force.
A net force is acting on the object, in the opposite direction to its motion.
If you have acceleration and Force, what equation do you use to find mass?
m = F divided by a
If the same force acts on something with a bigger mass, how does the motion compare to when it affects a smaller mass?
Bigger mass moves less.
Smaller mass moves more.
What is the net force for an object that is moving at a constant velocity in a straight line?
0
