Big Picture: Dynamics, collision, projectiles, ballistics, cars.
Principles: Newtons Law of Motion, the three laws of motion discovered by Isaac Newton.
1st Law of Motion: states that any moving object will continue moving until something stops it. For example, a car with no friction starts rolling, that car will continue rolling until it meets a wall or something to stop it.
2nd Law of Motion: states that in whatever direction you apply force,the object will move in that direction.
3rd Law of Motion: states that every reaction has an equal and opposite reaction.
This means that if a balloon is released with air inside the balloon will fly away because of the air released (As shown in the picture).
Friction: the force that an object has when rubbed on a surface. When you apply force the friction will be equal to the applied force, and the rougher the surface the more friction there will be.
Projectiles: are objects that are thrown or dropped and the only force acting upon it is gravity. For example if a cannon was shot and there was no gravity then that cannon ball would continue to move forward, but if the cannon was shot and there was gravity then that cannon ball would fall to the ground in a parabola motion. As shown in the picture to the right.
Key Words: Distance, Time, Height, Velocity, Friction, Projectile
Equations: Here are some of the equations we will use.
To find the time the ball was in the air use: 2(2*H/g)^1/2
To find the distance that the car traveled use: Vfinal=V0+A*T
H= Height of ball
D= distance traveled by car
T= time it takes the car to stop
A= acceleration
g= Gravitational force (9.81m^2)
V= Velocity
