position/time graph
On a position time graph, how do you determine how far an object is from where it started?
y- axis
On a velocity time graph, how do you determine how fast an object is moving?
y-axis
How do you approach a projectile problem?
x-y chart
What is acceleration?
change in velocity over time
What is the final vertical velocity equal to for a level angled projectile?
Vyf=Vyo
On a position time graph, how do you determine how fast an object is moving?
slope
On a velocity time graph, how do you determine which way the object is moving?
if its located above or below the x-axis
In projectile motion, what type of motion is each direction?
x=constant
y=accelerated
What is the acceleration of an object in free fall?
9.8m/s^2 going down
What is the velocity of a projectile at its peak?
Vpeak=Vx
On a curved position time graph, how do you determine instantaneous speed?
slope of tangent
On a velocity time graph, how do you determine how far an object travels?
area under the curve
What is the answer for the reason above of x=constant and y=accelerated?
x has no farces and y has force of gravity acting on it and forces cause acceleration
What variables tell you if an object speeds up or slows down and how do they tell you?
velocity and acceleration
same sign=speeding up
opposite sign = slowing down
What is the acceleration of an object at the peak of an upward throw?
g(9.8 m/s^2)
On a curved position time graph, how do you determine average speed?
slope of secant
What motion variable cant you determine from a velocity time graph?
final position
What is the equation for Vx for an angled projectile?
VCos theta
Which variable shows the direction of the objects motion?
velocity
On a position time graph, how do you determine how fast an object is moving?
if its moving away or towards the x-axis
What is the slope of a velocity time graph?
acceleration
What is true for all horizontal projectiles?
Vyo=0
a=g
How do you calculate velocity when an object is moving at a steady speed?
change in position over time
