Sci

• Scalar - has magnitude only, to get the sum of the scalar quantities, you simply get the algebraic sum of their magnitudes
• Vector - has both magnitude and direction, to get the sum of the vector quantities you simply get the algebraic sum of the magnitudes.
• x component - a vector represents how far the vector goes in the horizontal direction.
• y component - a vector represents how far the vector goes in the vertical direction.
• Vector quantities - have magnitude and direction.
• Resultant vector - is a combination or in simpler words, can be defined as the sum of two or more vectors which has its own magnitude and direction.
• Pythagorean Theorem - is a fundamental principle.
• Momentum - It is the product of mass and velocity of a moving subject.
• Impulse - The net force acting on an object is equal to the rate of change in an object's momentum over time.
• How can we change the Momentum of an object?

  Increasing Momentum and Decreasing Momentum.
• Collision - It also shows one of the fundamental laws in physics the law of conservation of momentum.
• Elastic Collisions - Occurs when objects strike each other and no deformation occurs.
• Inelastic Collisions - Occur when objects strike each other and stick together.
• Work - is defined as a force acting upon an object to cause a displacement.
• d = displacement
• angle = theta
• Power - rate of energy transfer.
• Energy - ability to do work
• Mechanical energy - is the energy which is possessed by an object due to its motion or its stored energy of position.
• Kinetic energy - Is the energy of motion
• Potential energy - an object can store energy as the result of its position
• Gravitational Potential energy - associated with an object at a given location above the surface of the earth.
• Elastic potential energy - can be thought of as the energy stored in the deformed spring
• Projectile motion - is a form of motion in which an object or particle is thrown near the earths surface, and it moves along a curved path under the action of gravity only.
• Projectile

  an object in projectile motion
• Trajectory

  path that the projectile follows
• Peak

  Highest point that the projectile could reach during its motion
• Range


  The horizontal displacement of the projectile from its initial position in which its vertical displacement is zero
• Parabola

  Shape of the path of a projectile.
• Derivation of projectile motion


  an object is projected at an angle with respect to the horizontal, the velocity of the projectile
• Parabolic


  Path traced by an object accelerating only in the vertical direction while moving at constant horizontal velocity.
• Heat


  as the form of energy that can be transferred from one system to another as a result of temperature difference.
• Thermodynamic analysis


  is concerned with the amount of heat transfer as a system undergoes a process from one equilibrium state to another
• Heat Transfer


  The science that deals with the determination of the rates of such energy transfers
