Study Notes
Newton's Second Law
- A plastic ball and a wood ball collide, both will change direction.
Projectile Motion
- In a projectile motion, the angle of an object’s initial velocity with respect to the range is called the angle of elevation.
- Projectile motion reaches maximum displacement (x) when θ = 45°.
Collisions
- An elastic collision happens when two billiard balls collide with the same amount of force.
- Perfectly elastic collision occurs when both balls move with the same velocity after collision.
- Inelastic collision happens when two objects collide and stick together.
- Perfectly inelastic collision occurs when two objects collide and completely lose their kinetic energy after collision.
Force and Motion
- A moving object is impacted by balanced forces if it is constantly accelerating, has the same speed, or is not moving.
- The force acting against weight is called a normal force.
- Friction is a force that opposes motion.
- Applied force is a force that is applied to an object.
Energy
- Kinetic energy is the energy of a moving object.
- Potential energy is the energy of an object at rest.
Units and Conversions
- 18 mm is equal to 0.71 inches.
- 185 yd per minute is equal to 6.31 mi/h.
- 186,000 mi/h is equal to 2.82 billion km/yr.
Scientific Notation
- In scientific notation, the exponent is positive if the decimal point moves to the left.
The Titanic
- The Titanic, a steam-powered cruise ship, was travelling at 14,444.44 m/s to travel a distance of 650 kilometers in 45 seconds.
- The iceberg had a mass of 4,500 kg, and it was travelling at 175 m/s.
