Study Notes
Force
- Force is calculated using Newton's second law of motion: Force = Mass x Acceleration
- This means that the force acting on an object is directly proportional to its mass and acceleration
Velocity, Acceleration, and Time
- Velocity = Initial velocity + (Acceleration x Time)
- This equation shows that the final velocity of an object is equal to its initial velocity plus the product of its acceleration and the time it accelerates for.
Work
- Work = Force x Distance
- This equation shows that the work done by a force is equal to the force applied multiplied by the distance over which the force is applied .
Gravitational Potential Energy
- Gravitational Potential Energy = Mass x Gravity x Height
- This equation shows that the gravitational potential energy of an object is equal to its mass, multiplied by the acceleration due to gravity, and the object's height above a reference point.
Conservation of Momentum
- Initial Momentum = Final Momentum
- This equation represents the principle of conservation of momentum which states that the total momentum of a closed system remains constant. In simpler terms, the total momentum before a collision is equal to the total momentum after the collision, with momentum being given by the product of mass and velocity.
