This is a property of matter which causes massive objects to resist movement very well.
What is inertia?
100
Fnet divided by the acceleration of an object is equal to this.
What is mass?
100
For every action there is an equal but opposite one of these. :)
What is a reaction?
200
The area under a v-t graph is equal to this.
What is displacement?
200
This force is what pushes against an object's motion once it is already moving. (Be specific)
What is kinetic friction?
200
If net force is equal to this, an object can be moving at a constant speed.
What is zero?
200
An object with a larger mass running into an object with a smaller mass will cause the smaller mass to move away with a ____________ acceleration.
What is higher?
200
Even though there is a reaction force that is equal to the action force, an object can still have a net unbalanced force because the forces act on ___________ .
What is "on different objects". (each other).
300
The slope of a position vs time graph is equal to this.
What is velocity?
300
This force exerts itself at a distance and varies with an object's mass.
What is gravity?
300
If going around a curve at a constant speed, your body wants to go off in this direction because of Newton's 1st law.
What is at a tangent?
300
A 12 N net force will cause a 3 kg object to move away with this acceleration.
What is 4 m/s^2.
300
As you break to come to a stop in your car, your body pushes into this. As a result, this pushes back into you to stop your body.
What is a seatbelt?
400
This can be found by taking displacement over time (OR by (v1+v2)/2 if the object is accelerating at a constant rate).
What is AVERAGE velocity?
400
This force acts from the ends of a rope toward the center.
What is tension?
400
If I push backwards while inside my car, I won't change the velocity of my car because the force is not this.
What is an external force?
400
This is what is required in order to accelerate an object.
What is a net unbalanced force?
400
The force from this is the reaction force which allows us to walk.
What is the floor (ground)?
500
This is the equal to the slope of an acceleration vs time graph.
What is jerk?
500
This is how much net force will be exerted when 3 N pull on an object to the right and 4 N pull up on an object.
What is 5 N [up to the right]?
500
When I push on a wall, the wall doesn't move because the forces are this.
What is balanced?
500
An object which is not accelerating will have this net force.
What is zero?
500
A 70 kg person exerting a 30 N force on an 100 kg person will have this force exerted back on her.
