Projectile motion
curved motion
Characteristics of curved motion
Displacement of curved motion
speed of curved motion
properties of curved motion
Uniform speed motion
speed direction change
The direction of acceleration remains unchanged
Conditions for objects to move in curves
Conditions for curved motion
The resultant force is not necessarily constant force
The speed will change
The direction of the resultant force (direction of acceleration) and the direction of velocity are not collinear
The initial velocity is not zero
The net force is not zero
Different directions
Movement trajectory direction
The resultant force is directed towards the concave side of the trajectory
The relationship between the direction of the resultant force and the magnitude of the speed
When the two form an acute angle, the velocity increases
When the two form an obtuse angle, the velocity decreases
When the two are perpendicular, the speed remains unchanged (only the direction changes)
Synthesis and decomposition of movement
Combined motion and partial motion
The actual motion of an object is composite motion, and the several motions it participates in are component motions.
Vector synthesis and decomposition
The resultant force is 0. If one force is removed, the resultant force of the remaining forces will have equal and opposite directions.
Equivalence
Isochrony
Movements occur simultaneously
independence
consubstantiality
Link speed issues
The rope and rod correspond to the same speed, decomposing the actual movement.
Boat crossing problem
shortest time problem
shortest path problem
The resultant velocity is perpendicular to the river bank
The resultant velocity cannot be perpendicular to the river bank
Solve by drawing a circle
flat throw motion
The definition and properties of flat throw motion
The initial velocity is horizontal. The initial velocity cannot be 0. The object moves only under the influence of gravity.
Flat throwing motion is actually a uniform curved motion with acceleration g
Research methods and rules of flat throwing motion
The horizontal throwing motion is divided into free falling motion in the vertical direction and uniform linear motion in the horizontal direction.
The time of flat throwing motion is only related to the height of fall
The speed of flat throwing motion
level
vertical
Resultant speed
speed change
Displacement of flat throwing motion
horizontal direction
Uniform straight line
Vertically
Uniform speed straight line
total displacement
parabola
***Calculation of trajectory equations
Two Corollaries of Flat Throwing Motion
angle conclusion
midpoint conclusion
Combination of flat throwing motion and inclined plane
Hit vertically onto the slope
Throw it horizontally from an incline and hit it onto the incline
Note that there is a conclusion farthest from the slope
The farthest time is half
The furthest point is the midpoint of the displacement along the slope
general projectile motion
Throw diagonally upward
