This video explains Newton's third law of motion. For every action there is an equal and opposite reaction. One of many examples of this is shown when birds fly. Also, sitting in a chair is an example of Newton's third law. When we sit in a chair our body exerts a downward force on the chair therefore the chair also exerts an upward force.
In this video he explains that Newtons second law is that acceleration of an object that depends on the mass of the object and the amount of force applied. Newtons second law of motion equation is Force= Mass x Acceleratuion. He explains that the more mass an object has the slower it moves and an object with less mass the faster it moves. Therfore, we need to apply more force for an object with more mass to move faster. Finally, if someone applies more force to an object the faster an object is, compared to if you apply less force to an object the slower an object is.
In this video you will learn about position,velocity, and acceleration. You will learn the difference between distance and displacement. You will be able to know the differencance and the definition of scalar and vectors. Also, you will learn the diffenrence between velocity and speed. Finally, you will know the equatuions for average speed and velocity.
In this video you will learn about the first law of motion. The first law of motion expains that an object in motion will stay in motion. That an object in motion must be acted by a force.The force of friction makes an object stop.Finally, if an object moves it soon will end up at ret.
This short clip describes what physics is or means. Physics is basically the question of how things work. Physics is the "how",for instance how things moved or what made these things move. Physics also, have to deal a lot with mathematics. Mathematics helped answer the "how" question from different questions asked about physics. You involve every thing you learned from previous years in math to figure out the how in physics.
