Science

• A Force is a push or pull on an object.
• Forces that result from physical interaction is called Contact Forces.
• Some forces also act within a certain distance, such as a magnet pulling a piece of metal or an object that falls from above due to gravity. The forces responsible for these effects are called Distance Forces or Noncontact Forces.
• Balanced Forces are two equal forces acting on an object in opposite directions.
• Unbalanced Forces are two unequal forces acting on an object.
• Weight is the measure of the force of gravity on an object.
• Mass determines the amount of a material in an object.
• Gravity is a force that pulls or attracts all objects toward each other.
• According to legend, he discovered the force of gravity which is Sir Isaac Newton. Eventually, he would formulate a law called the Universal Law Of Gravitation.
• Friction is a special kind of force that acts in the opposite direction as the applied force.
• Static Friction happens when the surfaces of two objects that are at rest are in contact with each other.
• Kinetic Friction is a friction that acts between a moving object and the surface where it is moved.
• Lubricant is a substance that provides a thin slippery film between the parts that rub together.
• Law Of Inertia, the object will remain at rest unless an outside force will make it move.
• Law Of Acceleration show that if the same amount of force is exerted on two objects with different masses, the result of the acceleration will also differ.
• Law Of Interaction or the Law Of Action and Reaction means that for every action, there is an equal and opposite reaction.
