4th sum Science Flashcards
-also known as the law of acceleration
-states that the acceleration of an object by a force is inversely proportional to the mass of the object and directly proportional to the force
-Force = mass x acceleration
Newton’s Second Law of Motion
a form of motion where an object given an initial velocity is thrown or projected and is allowed to be acted on by gravity in a curved-like path
Projectile Motion
curved path followed by a projectile
Trajectory
the object/person being thrown upward
Projectile
projectiles that are launched with an initial velocity from an elevated position and follows a curved-like path to the ground
Horizontally Launched Projectiles
launched at an angle with respect to the horizontal and rises to a peak while moving horizontally
Angle Launched Projectiles
angle launched projectile exhibits a full parabolic trajectory motion
Parabola
-highest point in a projectile’s motion
-once a projectile reaches the apex, the acceleration drops to a 0
Apex
-x component
-neglects air resistance
-constant horizontal velocity (Vx/Vi)
-horizontal acceleration is 0 (ax)
-Range is also known as the horizontal distance (dx)
Horizontal Motion
-y component
-force acting upon this motion is the force of gravity (g=ay=ag= -9.8 m/s2)
-vertical velocity is not constant (Vy/Vi)
-Height is also known as the vertical distance (h=dy)
Vertical Motion
3 Primary Factors Affecting Trajectory
•Projection Angle
•Projection Velocity
•Projection Height
release angle
Projection Angle
initial or the take off velocity
Projection Velocity
above or below landing
Projection Height
