An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an unbalanced force
What is newton's first law of motion
100
According to Newton, this is produced when a force acts upon a mass.
What is acceleration
100
When you jump, you push on the ground with your feet (action force). What is the reaction force being applied back?
What is the ground pushing back on you.
200
The SI unit used to measure a force
What is a newton
200
These two factors affect the gravitational attraction between two object.
What is mass and distance
200
Because of this, Earth stays in motion around the Sun and the moon stays in motion around the Earth.
What is inertia
200
Mr. Newton said that you can incrase the acceleration on any object by changing these two factors
What is force and mass
200
A hammer exerting a force on a nail and the nail exerting a force back is an example of what?
What is Newton's Third Law
300
Combination of all forces acting upon an object
What is net force
300
This Law states that all objects in the universe are attraced to each other.
What is Law of Universal Gravitation
300
The amount of inertia an object has depends upon this factor.
What is the amount of mass the object has
300
Keeping the force constant, how can you make an object accelerate?
What is decrease the mass
300
Newton's third law of motion
What is......For every action there is an equal but opposite reaction.
400
Net force applied to an object that causes the object to start to move, stop, or change direction.
What is unbalanced force
400
This is a measurement of the amount of gravitational pull on an object at a planets surface.
What is weight
400
When diagraming a force being applied to an object we use arrows. What do the arrows represent?
What is the strength and direction of the force being applied.
400
Newton expressed his second law in this equation
what is F=MA
400
According to Newton's third law, when a force is applied to an object, the object applies an equal force back. Why don't these two forces cancel each other out?
Because they are acting upon different objects.
500
Equal forces acting on one object in opposide directions. Each force is balanced by the other.
What is balanced force
500
A type of fluid friction that objects experience as they are in free fall.
What is air resistance
500
When the force of air resistance equals the the weight of the object in free fall, we say the object has reached this.
What is terminal velocity
500
What is the net force on a 6300 kg object accelerating at 8m/s
What is 50,400N
500
What is the force being applied to an object that weighs 1.3kg at a rate of .02m/s?
