1、 The motion of a particle (1) ---- linear motion 1) uniformly variable speed linear motion 1. Average velocity vplane = s / T (definition) 2. Useful inference VT ^ 2 – VO ^ 2 = 2As 3. Middle time velocity VT / 2 = vplane = (VT + VO) / 2 4. Final velocity VT = VO + at 5. Middle position velocity vs / 2 = [(VO ^ 2 + VT ^ 2) / 2] 1 / 2 6

Chapter 1 force gravity: g = mg friction: (1) sliding friction: F = μ FN, that is, sliding friction is proportional to pressure. (2) static friction: ① the calculation of general static friction should use Newton's second law, remember not to use f = μ FN indiscriminately. (2) there is a formula for the calculation of maximum static friction: F =

As long as the compulsory two, not compulsory one! To all

The following are important:
Projectile motion: vertical upward: S = vot-1 / 2GT & sup2
Vertical drop: S = VOT + 1 / 2GT & sup2
Horizontal throwing motion: T = 2H / G under the root sign, (H is the vertical distance from the starting point to the end point)
Horizontal displacement x = VOT = 2H / G under VO radical
Vertical displacement y = gt & sup2 / 2 = h
Final velocity VT = VO & sup2; + 2GH under root sign
Total displacement: S = x & sup2; + Y & sup2;
Horizontal displacement S = VOT = VO & sup2; sin2 θ / g
Vertical displacement of the highest point y = VO & sup2; sin & sup2; θ / 2G
Centripetal force: F = MV & sup2 / r = MW & sup2; r = MR4 π & sup2 / T & sup2;
Gravitation: F = GMM / R & sup2;
Gold substitution: F = GMM / R & sup2; = MV & sup2; / r = MW & sup2; r = MR4 π & sup2; / T & sup2; = ma
Kinetic energy: EK = 1 / 2mV & sup2;
Gravitational potential energy: EP = MGH
Elastic potential energy: EP = 1 / 2kx & sup2;
Theorem of kinetic energy: w = 1 / 2mvt & sup2; - 1 / 2mvo & sup2; (very important! Remember)
Mechanical conservation: EK1 + EP1 = Ek2 + EP2
Power: P = w / T = FV = Fv (at maximum speed, acceleration is 0, traction force F = friction force F, be sure to remember.)

What are the formulas of physics compulsory two in senior one

Do you have all the formulas of physics compulsory 2 in senior one? They should be very comprehensive

When a cup is filled with milk, people will say it is milk; when a cup is filled with juice, people will say it is juice; only when the cup is empty, people will see the cup and say it is a cup,

Do you want to write a composition? The proposition is very clear. When we help you with everything, you find your weakness. When we help you, the composition obviously conceals your light

For example, gravity is equal to centripetal force, that is, when a free falling body is equal to this kind of equivalent force, what else is there? For example, in what situation, what force will be equal to what force formula is, what words to choose to see what words to use? What types of formulas are mainly about collision electric field, magnetic field and belt transport type. I will add points when I understand

Only circular motion has centripetal force, and free falling body is gravity
Do force analysis, first draw all the forces on the object, and then analyze whether the resultant force is zero, the magnitude of the resultant force, and so on according to its motion state

I can't understand the explanation in the reference book

You should know that kinetic energy is equal to 1 / 2 MV ^ 2, then 0-1 second, the speed keeps increasing, kinetic energy increases, indicating that the combined external force does positive work. 1-3 seconds, the speed keeps decreasing, kinetic energy decreases, indicating that the combined external force does negative work

Is the module length of a vector equal to a scalar? If the module length of a vector is equal to 1 and the scalar is 1, is the module length of a vector equal to a scalar? If not, is it because it is the module length of a vector, so it contains direction?

The module of a vector is non negative and the scalar is R. in the problem you mentioned, the module length has no direction, which means the size. If the module length of a vector is equal to 1 and the scalar is 1, then the module length of a vector is equal to the scalar size
