Position vs. time
a horizontal line means...
the object is at rest
a horizontal line means...
the object has a constant velocity
Newton's Law is the law of ____, which has to do with an objects... ___________.
inertia; mass
What number is always included when finding the gravitational force between two objects?
G = 6.67 x 10^-11
initial velocity is 0 m/s
acceleration is -9.8 m/s^2
a non-zero slope means...
the object has a constant velocity
a non-zero slope means...
the object has a constant acceleration
Newton's 2nd law is...
F = m x a
If one mass were to increase, then the force would...
increase
if you are given the initial velocity, the distance, the acceleration, and you're trying to find final velocity, which equation would you use?
timeless
a negative slope means
the object is moving at a constant velocity in the negative direction
crosses the x-axis
Newton's 3rd law is known as the law of...
opposite forces
In the ULoG equation, distance is always
squared
If you are given the time, acceleration, initial velocity, and you're asked to find distance, which equation would you use?
no final velocity
If there is a curve in a position vs. time graph, then the object is
accelerating
traveling in the negative direction, slows down and stops, then speeds up in the positive direction
How would you find the acceleration of an object?
find the net force, then divide by the object's mass
If the distance between two object's doubles, how would that affect the force?
it would decrease by 1/4
If you're given the initial velocity, the final velocity, and the time, how would you find acceleration?
vf-vi/t = a
how would you find the velocity of an object in a position vs time graph?
find the slope
how could you tell what the acceleration of an object is...
If there is no net force on an object, will it move? Explain.
If it is at rest, no, it will not move. If it is in motion, it will keep moving at a constant speed. The object just won't accelerate.
What celestial body has the greatest affect on Earth? The Moon or the Sun? Why?
The moon because it is closer.
If you had a changing velocity, could you use kinematics equations
no; they only deal with a constant acceleration
