Physics of Motion
The unit that is used to measure Force.
What is a Newton (N)
What is Newton's first name?
Isaac
What is Newton's Third Law?
Forces occur in pairs - equal magnitudes and opposite directions.
How do you calculate an object's speed?
Distance divided by time.
What number do we us for gravitational acceleration, represented by "g"?
What is 9.8 m/s2
The energy present in all MOVING objects.
What is Kinetic energy
Which Newton's Law States: "An object in motion tends to stay in motion, an object at rest tends to stay at rest"?
What is Newton's First Law?
Name TWO forces acting on a ball that has been thrown in the air.
What is Air Resistance and Gravity.
Newtons first law
An object in motion will stay in motion, and an object at rest will stay at rest, unless acted upon by an outside force.
Which city in the world hosted the Summer olympics this summer?
Tokyo
What are two things that increase an objects Potential Energy?
What is Mass and Height.
What "attractive" force acts between two objects?
What is gravity.
The difference between weight and mass
Mass is the amount of matter or stuff making up an object, weight is the amount of gravitational force on that object.
What is the difference between speed and velocity?
Speed only shows how fast an object is going, velocity describes the speed and direction.
What is Captain America's real name?
Steve Rogers
What unit is used to measure energy?
What is the Joule (J)
What equation for Force is described by Newton's Second Law?
What is F = M x A
I drop a 5 oz baseball and a 10 lb rock from the same height, which hits the ground first?
they hit at the same time
What is the force that opposes gravity that acts on an object sitting on a counter (what force is pushing back up)?
What is normal force?
How many curves are there in a standard paper clip?
3
If a Car is traveling at 40 m/s for 10 s what is the distance it will travel?
D= S x T
D= 40 x 10
D= 400m
What is the mass of an object that is accelerating at 20m/s2 with a force of 10,000N?
M = F/A
M= 10,000 / 20
M= 500kg
Does your weight increase or decrease on the moon? Why?
Weight will decrease, less gravitational pull.
How you can you describe what one Newton of force feels like to you?
100 grams being held in your hand.
What temperature does water freeze at?
32 deg F (or 0 deg C)
