Change in velocity
----------------------
Change in time
Projectile motion - answer✔Display two types of motion simultaneously
dx= Vxt
dx- horizontal distance
Vx- a function of velocity
t-time
Vertical motion - answer✔d= 1/2 at^2 + Vit
Force - answer✔a push or pull on an objet
Newton's first law of motion - answer✔A body at rest will remain at rest, and a body in motion
will remain in motion with a constant velocity, unless acted on by an unbalanced force.
Newton's second law - answer✔an unbalanced force will cause acceleration, and this
acceleration is directly proportional the the unbalanced force.
F=k(or m)a
F-force
k- the content of proportionality= the mass of the object
a-acceleration
