Movement
What is the Final Position - Initial Position?
Displacement
What is Newton's First Law?
An Object at rest stays at rest unless a force is acted upon it. An object in motion stays in motion unless a force is acted upon it.
What is the difference between scalar and vector quantities?
Scalar quantities have just a magnitude and Vector quantities have a magnitude and a direction.
What is Newton's Second Law?
Newton’s second law states that the acceleration produced by a net force on an object is directly proportional to the magnitude of the net force, is in the same direction as the net force, and is inversely proportional to the mass of an object.
The four main types of matter.
Solid, Liquid, Gas, and Plasma
What is the Change in Position over the time interval?
Velocity
_________ is a measurement of Inertia.
Mass
The ____________ rule is used to add two vectors going in different directions.
Parallelogram
What is the unit of measurement for Force? What do we get when we break down that unit even further?
Newtons
kg x m/s^2
Which is faster?
The Speed of Light
or
The Speed of Sound
The Speed of Light!
What is the slope of a Velocity-Time Graph?
Acceleration
Is it more accurate to say that a dieting person loses mass or loses weight?
Lose mass.
There are two parts to this question.
I would like a volunteer from each group.
The answers.
If we double the Net Force acting upon an object without changing its mass. What happens to the acceleration?
The acceleration will double.
What are the 8 planets in our Solar System? (In Order)
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
Shunxy drops their book off of a building. It hits the ground below after 1.5s.
Find the speed when it hits the ground AND how high is the building.
14.7 m/s
11.03 m
Asteroids have been moving through space for billions of years. What keeps them moving?
Pull of gravity and Object in motion stays in motion...
If a projectile is launched at a 45* angle and what do we know about the horizontal and vertical components?
They are the exactly the same!
Suppose you exert a horizontal push on a crate that rests on a level floor, and it doesn't move. How much friction acts compared with your push?
It has the same magnitude as your push, oppositely directed, producing a zero net force.
What are the three additive primary colors of light?
Red, Green, and Blue
You spot a bear charging at you, so you instantly start running at 6.26 m/s but after some time you start to tire, and you decelerate at a rate of 0.72 m/s2. Ultimately the bear catches up to you and attacks you (Oh no!) If it only took the bear 5.52 s, what was your final velocity before the bear mauled you?
2.29 m/s^2 :(
As Earth rotates about its axis, it takes three hours for the United States to pass beneath a point above Earth that is stationary relative to the sun. What is wrong with the following scheme? To travel from Washington D.C. to San Francisco using very little fuel, simply ascend in a helicopter high over D.C., and wait three hours until San Francisco passes below?
The helicopter has the same horizontal speed as Earth's surface. When it ascends, it keeps this horizontal speed and moves with Earth below.
A bowling ball is moving at 10 m/s when it rolls off the edge of a tall building. What is the ball's speed one second later?
14.00 m/s
Using Newton's Second Law, explain how objects fall at the same rate.
All freely falling objects fall with the same acceleration because the net force on an object is only its weight, and the ratio of weight to mass is the same for all objects.
