SCI W1 Projectile Motion Flashcards
A body in motion remains in motion or a body at rest remains at rest, unless acted upon by a force.
1st Law (Inertia)
For every action, there is an equal and opposite reaction.
3rd Law (Interaction)-
Force equals mass times acceleration: F=m*a
2nd Law (Acceleration
Force is acting on the projectile.
Gravity
Any object that continues in motion by its own inertia and is influenced only by the downward force of gravity (and air resistance)
Projectile
The path that the projectile follows.
Parabola
The path
Trajectory
Neglect air resistance
Horizontal Motion
If there is no force acting on an object then it will continue moving at a constant speed.
Horizontal Motion
Horizontal acceleration is
is 0
Has constant speed
Horizontal Motion
Horizontal distance is
Range (dx)
The force acting upon in this motion is the force of gravity (g=ay=ag) (g= -9.8m/s2)
Vertical Motion
Has acceleration
Vertical Motion
Vertical distance is
the height (h=dy)
