Physics of Motion
The unit that is used to measure Force.
What is a Newton (N)
What is Newton's first name?
Isaac
What two factors do you need to determine the momentum of an object?
What are mass and velocity?
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 light wave has the most energy a radio wave or a gamma ray?
What is a gamma ray?
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 the potential energy of a 5 kg rock held at 50 m above the ground?
What is 2500 N?
What unit is used to measure velocity?
What is meters per second (m/s)
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 is acting on a falling object ?
What is air resistance?
How many curves are there in a standard paper clip?
3
If a car travels at 40 m for 10 s what is the velocity of the car?
V= m/s
V= 40/10
V= 4 m/s
What force will an object experience if it has a mass of 500 kg and is accelerating at 20m/s2?
F= M * A
M= 500 * 20
M= 10000 N
Does your weight increase or decrease on the moon? Why?
Weight will decrease, less gravitational pull.
What it the unit used to measure frequency?
What is hertz (Hz)?
If carbon-14 has a half life of 5730 years, how old would an object be that has experienced 4 carbon-14 half lives?
What is 22,920 years?
