Physics 10

• Weight is the gravitational pull on an object, measured in Newtons.
• Work done = force x distance moved
• A newton is defined as the amount of force required to accelerate an object with mass equal to one kilogram at a rate of one meter per second squared
• Energy can be transferred from one object to another by work done or heat transfer.
• Newton's third law of motion states that for every action, there is an equal and opposite reaction.
• Newton's second law of motion describes how the velocity of an object changes when it is subjected to an external force.
• The SI unit of force is the Newton (N)
• The SI unit of energy is the joule (J).
• Newton's first law of motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
• The SI unit of force is the Newton (N)
