Fig NEWTON
The law that states for every action there is an equal and opposite reaction
What is Newton’s Third Law?
You know an object is moving when its position relative to a fixed point called ________is changed.
What is a reference point?
Forces that would stop an object in motion? (2)
What are friction and gravity? (among others)
When spinning the fidget spinner, it eventually slows down. ____ is demonstrated.
What is air friction?
It is a pull not a push
What is gravity?
Law that states an object's motion won’t change unless acted upon by a force
What is Newton's First Law?
The speed of an object in a specific direction
What is velocity?
The force exerted on an object due to gravity.
What is weight?
When a coin is put in a blown-up balloon, when set in motion the balloon moves unpredictably. Why?
What is the unbalanced center of gravity.
What happens when two balanced forces oppose each other
What is nothing?
As the _____of an object grows, its______ also grows.
What is inertia?
The force exerted on an object due to gravity.
What is weight?
The sum of forces acting on a object
What is net force?
In the demonstration with the box, the magnets and the string the magnets were sometimes able to stay up without touching. What two main factors contributed to the outcome of this experiment?
What are mass/strength of the magnet and distance
Time divided by distance
What is the formula for speed?
Law that states acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object
What is Newton’s Second Law?
🔼V/ 🔼T
What is the formula for acceleration?
The force that acts on an object in order to direct it towards a center of curvature
What is centripetal force?
When leaning two cards against each other they are able to stay up until...
What is an unbalanced force?
Determines the amount of gravitational force something has.
What is matter?
The two ways to increase the acceleration of an object
What increases the mass or increases the force?
___________ is the product of mass and velocity, or in other words, inertia in motion.
What is momentum?
How are action and reaction forces related
What is action and reaction forces are always equal in magnitude but opposite in direction?
(For every action force exerted on an object, there is an equal and opposite reaction force exerted by that object on another object).
In Newton’s cradle, when the ball comes down on one side, the one on the opposite end comes up, and it then continues to swing until air friction takes over. Which two of Newton’s laws are demonstrated?
What are Newton’s first and third laws of motion (also the Law of Conservation of Momentum)
The total momentum of the objects in a closed system stays constant.
What is the law of conservation of momentum?
The resistance to change in motion.
What is Inertia?
Mass in motion.
What is momentum?
The way you keep an object’s acceleration the same if the force acting on the object is doubled.
What is you must double the mass as well?
(as per Newton's second law of motion (F = ma))
In the tennis ball drop experiment, the pie tin was moved out from under the ball, which then fell directly down into the cup. Name at least 3 forces that were demonstrated.
What are normal force, applied force, gravity, and friction?
You can't feel it, only changes in it
What is motion?
