1st Law
Inertia
The equation for newton's 2nd law.
What is F=m*a?
Each time you push down on the ground, the ground ______ back on your foot.
What is pushes?
This term describes a push or pull on an object.
What is force?
The strength of this weak force is determined by the mass of an object and its distance from another object.
What is Gravity?
How fast something is going, in a specific direction.
EX: Joe is headed 35m/h headed SW.
What is velocity?
The greater the mass, the greater the _______ required to accelerate an object.
What is force?
The tires on a car push on the road, and the road pushes back on the tires.
What would be the reaction force?
What is the road pushes on the tires?
An object's tendency to resist an unbalance force, which increases with mass.
What is inertia?
What is the Law of Universal Gravitation
As you increase the ______ of an object, its inertia increases as well.
What is mass?
2 objects are being pushed with the same force, but one object is accelerating at a greater rate. What is the difference between the two objects?
What is the mass of the objects?
A swimmer pushes against the water, and the water pushes back on the swimmer, pushing her forward.
What is the action force?
What is the swimmer pushing against water?
The sum of all forces acting on an object.
What is net force?
This is the unit used to measure force.
What is a Newton?
This is the type of force that opposes gravity when the object is at rest on a surface.
What is the Normal Force?
These two variables have a directly proportional relationship (when one goes up, so does the other).
What is Acceleration and Force?
When a jellyfish is swimming, their body is pushing DOWN against the water. In turn, the water pushes __________ against their body allowing them to swim.
What is UP?
This term describes the downward force exerted on a mass as a result of gravity.
What is weight?
If you push a book across the table, it will continue in motion at a constant speed until this force stops it.
What is friction?
The formula to calculate speed.
What is Distance / Time?
These two variables have a inversely proportional relationship (when one goes up, the other goes down).
What is Acceleration and Mass.
You and your friend, are playing tug of war. Your friend pulls with a force of 55 N, to the right. You pull with a force of 65 N, to the left. What is the net force on the rope?
What is 10 N to the left?
A contact force that resists the motion of two surfaces that are touching.
What is friction?
If you decrease the mass of an object, or increase its distance to another object, this force decreases.
What is gravitational force?
