Types of Forces
Anything that exerts a push or a pull is a ________
Force
The total length something travels is called ______
distance
An object has more gravity if it has more _______
mass (or height, but that's for later)
An object with a LOT of Inertia is the result of having a LARGE ________.
Mass
According to Mr. Yerrick, two opposing magnetic forces will ________ each other
attract
A force that opposes a force being applied to an object (2 surfaces rubbing past each other), this force is called _____
friction
Velocity is different from speed because velocity has _____
Direction
Galileo and Newton would both agree that if gravity is working on 2 differently sized objects, then what would happen if they were dropped at the same time?
They would fall at the same rate
Two magnets of equal size and the same charge push each other AWAY. This is an example of which law?
Newton's 3rd law (every action has an equal and opposite reaction)
If there were a North Magnet near a South magnet side by side, where would the field be strongest?
Between the North and South poles
When a force causes stretching and energy to be stored in a spring or rubber band this is called the ________ force.
elastic
The equation for velocity is ______
Velocity = distance / time
The frictional force due to surface area that opposes gravity is called ________
air resistance
In the 100 m sprint, the runner that can apply the greatest force and accelerate to the finish line wins. Which law does this reflect?
Newton's Second Law
Name one planet in our solar system that possesses a magnetic field.
Mercury, Earth, Jupiter, Saturn, Uranus
What is the unit for force?
Newtons
If you are moving BACKWARDS with respect to the frame of reference, then your velocity would be _________.
Negative
In terms of height, an object has more gravitational energy if it is _________ from the ground.
Higher/taller
Mr. Yerrick kicks his soccer hoverball down the hallway at a constant velocity. It slowly drifts until a student kicks it in a new direction. Which law is this?
Newton's first law
Where would a magnetic field be strongest?
At the northern pole
If a plane is flying with 200 N to the East, but the wind blows against it at 50 N to the West, then what is the resultant force?
150 N to the East
If you velocity is INCREASING, then we would call this _________
Acceleration
What are several factors that would allow you to overcome gravity as you move furniture?
You can calculate the acceleration of an object if you know force and mass using A = F/M . So if an object exerts 100N of force and has a mass of 20 kg, what is its acceleration?
100N/20kg = 5 m/s/s
If the Earth's mass were doubled, then what would happen to the distance from the moon?
It would become less (get closer)
