Speed- measures the number of distnace visited in a provided amount of time. (Doesn't measure the course of the travel) How quickly an object goes with respect to a frame of reference. You find speed by dividing distance by time. (Speed sama dengan distance/time) Instantaneous speed- the speed you happen to be traveling at that time, instead of a typical. Motion- enhancements made on position of the object, relative to a shape of research. Frame of reference- place or subject that you presume is fixed. You observe other items move simply by comparing those to that framework of guide. Velocity- a measure of the velocity and path of an subject. When speed, direction or perhaps both alter velocity alterations. If there is a rise in speed then simply positive speeding can effect. If there is a decrease in acceleration then adverse acceleration (deceleration) can effect. Acceleration= change in velocity/ time
Acceleration can involve a big change in the direction an object is moving. (Change in velocity over time) If the difference in velocity is definitely an increase = positive velocity. If the change in velocity is actually a decrease = negative velocity or deceleration. Lesson 1 . 02h Acceleration, Velocity, and Acceleration
Scalar quantities- a measurement that has a size or perhaps magnitude but no direction. (speed, time, heat & mass) Velocity and acceleration are certainly not scalar volumes. Speed is always positive.
Vector quantity- provides both value and a direction. (Velocity, acceleration and force happen to be examples) Magnitude- a measure of size, strength or volume.
Lesson 1 ) 03 The Laws of Motion
Natural Laws- Regulations that are established by nature and thus are valid everywhere. Force- a force or pull applied to an object.
Well balanced forces- The same in size and opposite in direction, cancelling each other away. They do not create a change in action. Unbalanced forces- They operate the same path. Cause a change in motion. The amount of force is usually not equivalent. Equal forces- Pushes in opposite direction, cancelling each other out therefore no movements occurs. The internet force is zero. Friction- a pressure that works resistant to the motion of an object. Pressure affects the movement of matter. Rubbing can occur between two solid objects and objects moving through a liquid or gas. (Force may resist the motion of the object causing it to slow down) Law of Inertia- an objects capacity a change in its motion. The greater the mass of an thing, the greater the force had to move that or stop it from moving. Net force- the whole of all the causes acting on an object.
Newtons first law of motion- two principles. An object that is not shifting will stay at rest unless a great unbalanced force acts onto it and a subject in action will stay in motion in a straight collection and at a consistent speed unless of course an unbalanced acts on it. It explains that a force is needed to change the motion of your object. Newtons second rules of motion- it says that the speeding of an object depends straight upon the internet force acting on the object, and on the mass of the object. Newtons third law of motion- For each action there exists an equal and opposite reaction that will happen. Lesson 1 ) 03h The Laws of Motion
Momentum- its the mass of the object times its speed. If the thing is not moving, it includes no impetus. Thw equation to find momentum is (momentum = mass x velocity) Momentum is actually a vector amount because the thing must be relocating a particular course. (p=mv) Momentum will remain constant for objects interacting with each other within a system. Angular Momentum- The energy characteristic of your rotating target, calculated by simply multiplying slanted mass moments velocity. They both handle the motion of objects and the dependence of mass on movement. The main difference is that linear momentum relates to motion along a straight line, and angular momentum handles rotational action. Like thready momentum, angular momentum is usually conserved within a system. the angular energy of an thing is...
