Newton's Laws
This law, also known as the law of inertia, states that an object in motion stays in motion unless acted upon by an external force.
What is Newton's First Law?
The formula for force is mass times this
What is acceleration?
In science, work depends on:
a. What is force and momentum?
b. What is force and distance?
c. What is acceleration and velocity?
d. What is displacement and speed?
b. What is force and distance?
D= s x t
What is 130 miles?
These can act as a medium through which a wave travels.
What are solids, liquids, and gases
This law states that the force on an object is equal to its mass times its acceleration.
What is Newton's Second Law?
It's the force that slows down or stops objects when they rub against each other
What is friction?
Pushing an object with all your strength but not being able to move it is an example of work.
What is no?
A light bulb that uses 100 J of energy every second.
The formula for power is:
p=w/t
This is the amount of power that is generated.
What is 100 W
These types of waves require a medium in which to travel
What are mechanical waves?
This law explains why when you push on a wall, the wall pushes back with an equal and opposite force.
What is Newton's Third Law?
The force that pulls objects toward each other, like how it makes things fall to the ground.
Forced is measured in these, which is named after the physicist who developed the laws of motion.
Jane applies 6 newtons to open a window 3 meters. This is how much work she is doing.
w= f x d
What is 18 joules
What are longitudinal waves?
According to this law, a soccer ball will not move until someone kicks it.
What is Newton's First Law?
The strength of gravity depends on these two things:
a. What is mass and distance between masses?
b. What is mass and velocity?
c. What is velocity and speed?
d. What is force and acceleration?
a. What is mass and distance between masses?
What is Potential energy?
Ben climbs a tree to retrieve a lost football. If he does 2,400 J of work to climb 8 m, how much force is he using?
w= f x d
What is 300 Newtons
Seismic waves are this type of wave.
What are surface waves?
This law can be used to calculate the amount of force needed to accelerate an object
What is Newton's Second Law?
The type of force is an upward force by a fluid that allows it to float.
a. What is gravitational force?
b. What is spring force?
c. What is bouyant force?
d. What is air tension force?
c. What is bouyant force?
This is energy in motion.
What is kinetic energy?
Bobby weighs 30kg and is standing on a cliff that is 3m high. This is how much potential energy Bobby has.
GPE= mgh
g= 9.8m/s^2
What is 882 joules
The distance between the crest of two waves is known as this.
What is the wave length?
