Honors Physics Test #1
In one dimension motion, left to right measures components in this direction.
In one dimension motion, up and down measures components in this direction.
change in position
Formula for displacement
Units for discplacement
Displacement is NOT this.
positive or negative
Displacement can be this or this.
Displacement by Time
Velocity is this divided by this.
The rate at which velocity changes
speed and/or direction
An object accelerates if it's these two things change.
Velocity by Time
Acceleration is this divided by this.
One uses these equations for motion with constant acceleration.
If something slows down, it's Vf is this.
If something starts at rest, it's Vi is this.
Position vs. Time Graphs tell you an object's....
A velocity vs. time graphs tells you an object's...
The area under a curve for a velocity vs. time graph is it's....
Free-falling objects undergo this.
There is no this in free fall, they are in a vacuum, such as space
acceleration due to gravity
Ag, or -9.81m/s² stands for...
Units for Velocity
Units for acceleration
Acceleration due to gravity on earth
Direction of object's acceleration is this even if the object is moving in an upward way.
If a ball is thrown upward, it's Velocity at the top is this.
Vi and Vf
If a ball is thrown upward, these two things are the same.
If a ball is thrown upward, this is it's Ag.
If the velocity and acceleration are in the same direction, the object [speeds up/slows down].
If the velocity and acceleration are in opposite directions, the object [speeds up/slows down].
If a ball is thrown upward, it has [velocity/acceleration] at the top.
If a ball is thrown upward, the initial and final velocities are the same, but these are opposite.
If something is being dropped, it's Vi is this.
magnitude but no direction
A scalar quantity has....
magnitude and direction
A vector quantity has..
speed, volume, area, temperature
Examples of scalar quantities
displacement, velocity, acceleration, force
Examples of vector quantities
Vector that represents the sum of two or more vectors.
An angle's name is always the [closest/furthest] direction followed by the other.
The resultant displacement includes these two things.
A speedometer on your car gives you the...
If something is falling, it's vertical change will always have a this in front of it.
constant and negative
A slope for the graph of a ball thrown vertically in the air should have a line pertaining to these two characteristics.
influence of gravity
Projectiles are objects that have been thrown or launched into the air and are subject to the this
In a full arc of a projectile motion, the Vy at the peak is this.
The Ay for a projectile motion is this.
Ax for projectile motion is this.
ΔX = 1/2(Vi+Vf)t
This kinematic equation cannot be used for projectiles.
The Y value for any horizontal launch (if it is traveling down) will always be this.
Viy, Ax, ay
These things are always constant for horizontal projections.
The hypotenuse can be calculated with this formula for projectiles.
For a horizontal projectile, the initial velocity of the projectile will always be this variable.
Normally, when dealing with projectiles, this will have to be calculated first.
The Ax is always 0 when you are at a...
The Vfy for launched projectile motions will always be this.
multiply time by 2
When dealing with projectile motions, you can't forget to do this.
