Force- any influence that causes an object to change. (This change can be movement, direction, or geometrical construction.)
Force is directly proportional to acceleration. So if force increases so does the acceleration and vice versa.
You can find the direction and magnitude of force acting on an object by plugging it into an equation.
1st law- An object in motion stays in motion unless acted upon by an unbalanced force. An object at rest stays at rest unless acted upon by an unbalanced force.
2nd law- Acceleration is produced when force acts upon a mass. Also the heavier the mass the more amount of force is required
3rd law- For every action there is an equal and opposite reaction. (For every force there is a reactive force that is equal in size but opposite in direction.)
speed- The distance traveled for the amount of time.
velocity- Rate and direction of motion.
Instantaneous speed- The velocity of an object at a certain time.
Instantaneous velocity- The rate and direction of motion at a certain time.
Average speed- the average velocity of an object.
Average velocity- The average rate and direction of motion.
Speed, velocity, acceleration, and momentum all effect one another. If you increase the speed of an object the velocity, acceleration, and momentum will also increase.
Velocity- V= v0 +at
Momentum- P=mv
All of this applies to our project because we are trying to calculate the height our roller coaster needs to be in order for the marble to go in a loop without anything covering it. (open loop)
