[LAB] Experiment 1: Kinematics Flashcards
Book Basis
When an falling object is not affected by any restraints like friction and air resistance, and falls under the influence of gravity alone, the object is said to be in ____________.
Free fall Motion
(object that is moving only because of the action of gravity)
The equation of motion for freely falling bodies are also same with ________________
uniformly accelerated motion.
Instead of using a (acceleration), acceleration due to gravity (g) is used and is set ______
constant.
Acceleration due to gravity formula
-9.8m/s^2
A form of motion experienced by an object or particle that is thrown near the earth’s surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are assumed to be negligible).
Projectile Motion
The objects maximum height is the _____
highest vertical position along trajectory (path)
The horizontal displacement of the projectile is called the
Range of the projectile
The range of the projectile depends on the object’s initial _____________
Velocity
Can be used to calculate where the ball will land when it is shot at an angle above the horizontal
Initial Speed
The maximum height of the projectile is given by the formula:
H = (Vosin0)^2 /2g
Horizontal range is computed using
R = Vosin0t’
t’ means
Time of flight
defined as the time from when the object is projected to the time it reaches the surfaces.
The time of flight projectile motion
This is twice the time to reach the maximum height
Symmetrical Projectile
The time to reach the maximum height is same with the time going down from maximum height to the ground. This is given by the formula:
t’ = 2Vosin0 / g
