This law states, "Every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force."
What is "Newton's First Law of Motion" or "The Law of Intertia"?
These two shapes are used in a free body diagram to represent an object.
What are squares and/or dots?
A push or pull exerted on an object that can cause it to change its motion
What is force?
This formula uses force, mass, and acceleration to mathematically express Newton's Second Law of Motion.
What is "f=ma" or "force equals mass times acceleration"
According to the second law of motion, increasing the acceleration of an object while keeping the same mass will have what effect on the object's force?
A free body diagram where all forces are balanced shows this movement.
What is none (no movement)?
The sum of all the forces acting on an object; the force that dictates the magnitude of an object's movement.
What is the net force?
If a cat weighing 5kg falls out of an apple tree (on earth) it will hit the ground with approximately this much force. (Be sure to include units.)
What is 49 newtons? (must have newtons)
The balloon rocket lab demonstrated Newton's Third Law of Motion which states this.
What is "every action has an equal and opposite reaction."
Draw a free body diagram for an apple falling off a tree with a force of 10N. Do not show air resistence.
What unit is equal to
1 kg* (m/s^2)
The net force of an object being pushed to the right with 30 N with 5 N of friction.
What is 25 N (to the right)
30 N - 5 N=25 N
A cat knocking a vase of flowers off the countertop is an example of these TWO (2) laws.
What are "Newtons First Law of Motion" AND "Newton's Universal Law of Gravitation" (or Law of Gravity)
If an object is moving to the right and experiencing friction, then friction will be drawn on a free body diagram going in this direction.
What is to the left?
A a contact force that surfaces exert to prevent solid objects from passing through each other.
What is a normal force?
If it takes 10.0 N to break an egg, and you drop an object on top of the egg; the object will need to weigh at least this many kilograms to break the egg.
What is 1.02 kilograms
10 N = (1.02kg) (9.8m/s2)
All three of Newton's Laws of Motion describe this phenomenon.
What is how objects move depending on forces applied to them. (Must mention objects, motion, and forces.)
Draw a free body diagram for a corvette that weighs 1664 kg traveling 35 meters per second to the left when it collides with a ford mustang that weighs 1623 kg and is travelling 35 meters per second to the right.
Bob-bot weighs 25 kg, Boot-bot weighs 30 kg, and Rob-bot weighs 45 kg. If all three bots are hit by a car weighing 1200kg at 12 m/s2; which bot will experience the greatest acceleration?
Bob-bot.
(all bots experience the same force, and force equals mass times accelleration, so the bot with the smallest mass will have the largest acceleration) F= 14,400 N so Bob-bot experiences 575 m/s2, Boot-bot experiences 480 m/s2, and Rob-bot experiences 320 m/s2)
A corvette that weighs 1664 kg is traveling 35 meters per second to the left. If it collides with a ford mustang that weighs 1623 kg and is travelling 35 meters per second to the right. What is the net force of the collision?
ForceCorvette = 1664 kg (35 m/s2) = -58,240 N
ForceMustang= 1623 kg (35 m/s2) = +56,805 N
ForceNet= -1,435 N (so moving left with 1,435 N)
Sally's mass is 30 kg. Her big sister Susie's mass is 80 kg. If Sally is on Earth and Susie is on The Moon, which sister weighs more?
gearth = 9.8m/s2
gmoon = 1.62m/s2
Sally's weight (force) = 30 kg (9.8) = 294 N
Susie's force = 80 kg (1.62) = 129.6 N
Sally is exerting more force.
