To consider after you have investigated Newton's Laws:
Why did Newton, an Englishman, write in Latin?
Who would be able to read his Principia Mathematica? Is this limited access fair? Why/whynot?
Newton's First Law
​
An object either remains at rest or continues to move at a constant velocity, unless acted upon by a force
​
​
​
Sum of forces = 0 Change in velocity dv/dt = 0
An object that is at rest will stay at rest unless a force acts upon it.
An object that is in motion will not change its velocity unless a force acts upon it.
The property where massive bodies resist changes in motion is called inertia

Collision Science
With no external forces, collisions can be inelastic where momentum is conserved
The total momentum of the objects prior to the collision equals the total momentum after.
In an inelastic collision the kinetic energy is not conserved by the colliding objects—some converted to sound, heat, etc.
Objects can collide and bounce off each other = elastic collision
An EXPLOSION occurs when objects are fragmented into many pieces. Momentum is conserved, KE increases. (There is conservation of energy because the KE is converted from PE)
​
Momentum is conserved
​
Final KE less than initial = inelastic collision
Initial KE = final KE = elastic collision
Final KE much larger than initial KE = explosion
