Physics for Science Olympiad Latest 2024 Graded A+ Newton's First Law Inertia: Every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. Newton's Second Law Force = mass * acceleration Newton's Third Law for every action, there is an equal and opposite reaction. Example: If object A acts a force upon object B, then object B will exert an opposite yet equal force upon object A. 7 types of forces 1) Weight (W) 2) Applied Force (Fapp) 3) Normal Force (N) 4) Tension (T) 5) Frictional Force (Ffrict) 6) Spring Force (Fspring) 7) Air Resistance (Fair) Applied Force Force which is applied to an object by another object. A person pushing a barrel is an example of applied force. Weight The force with which a body is attracted to Earth or another celestial body and which is equal to the product of the object's mass and the acceleration of gravity. A measure of the heaviness of an object. Normal Force the force that surfaces exert to prevent solid objects from passing through each other. Normal force is a contact force. If two surfaces are not in contact, they can't exert a normal force on each other. Tension the force transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the ends. Frictional Force the force generated by two surfaces that contact and slide against each other Spring Force the force that tends to retract the spring back to its original position. This force is called the spring force. It is a contact force that can be found in elastic materials Air Resistance the forces that are in opposition to the relative motion of an object as it passes through the air. These drag forces act opposite to the oncoming flow velocity, thus slowing the object down 3 types of acceleration uniform acceleration, non-uniform acceleration, and average acceleration uniform or constant acceleration change of equal velocity in equal intervals of time non-uniform acceleration the velocity of a body does not change at a constant rate in a given interval of time average acceleration the rate at which velocity changes Gravity a force of attraction that tends to draw
