Physics

• Force is the energy used to push and pull an object.
• Motion is the movement or change in position of an object resulting in force.
• Balanced force does not cause change in motion, net force is 0.
• Unbalanced force result in net force, causing acceleration or changes in motion.
• Contact force is the force exerted by an object due to its interaction with another object.
• Non contact force does not involve direct physical contact.
• Types of contact force include Muscular, Applied, Friction, Normal, and Tension.
• Friction forces are the force exerted by a surface where an object moves across it.
• Normal forces support the weight of an object and prevent it from passing through the surface.
• Tension forces are exerted by a rope, cable, chain, or any flexible connector that is pulled taut.
• Two types of Non Contact force are Gravitational force and Magnetic force.
• Sir Isaac Newton summarized the 3 law of motion: Law of Inertia, Law of Acceleration, and Law of Interaction.
• Law of Inertia states that an object at rest will remain at rest, an object in motion will remain in motion.
• Inertia of rest is when an object stays where it is placed.
• Inertia of Motion is when an object will continue at the same speed unless force act on it.
• Inertia of Direction is when an object will stay moving in same direction unless a force act on it.
• To find the net force, if the direction of the object motions is the same as the direction of the force, add the forces; if the direction of the object motions is different from the direction of the force, subtract the forces.
• Law of Acceleration states that force is directly proportional to acceleration, inversely proportional to mass.
• Work is defined as the product of the force applied to move an object.
• Gaspard Coriolis is a French Mathematician who is known for his work on work.
• Work is done when the object must move when force is applied and the direction of the object motions is the same as the direction of the force.
• Energy is the ability to do work.
• The greater the force you’re giving, the faster the object accelerates.
• The less the force you’re giving, the slower the object accelerates.
• The greater the mass of an object, the less it will accelerate.
• The less the mass of an object, the faster it will accelerate.
• Kinetic energy is the energy an object has due to its motion, while potential energy is stored energy that can do work when released.
• Energy can be transferred from one place to another or transformed into different forms.
• The SI unit of energy is the joule (J).
• Gravitational potential energy is the energy an object has because of its position relative to Earth's surface.
• Work done by a force is equal to the change in kinetic energy of an object.
• Potential energy is stored energy that can be converted into kinetic energy or other forms of energy.
• Elastic potential energy is the energy stored in stretched or compressed objects.
• Power is the rate at which energy is used up or produced.
• Work done = Force x Distance moved by the object
• The formula for power is Power = Energy / Time taken.
• Chemical potential energy is the energy stored in chemical bonds between atoms.
• Force: Energy used to push and pull an object.
• Motion: Movement or change in position of an object resulting in force.
• Balanced force: Forces that do not cause a change in motion, with a net force of 0.
