Physics

1. Mass and weight

1.1. The mass of an object is the amount of matter it contains.

1.2. The weight of an object is the force that pulls that object to the ground

2. Moment of Force (Gurna)

2.1. The product of the perpendicular distance from an axis of rotation to the line of action of the force and the magnitude of the applied force is called the torque of the force about that point. (Nm)

3. Pressure

3.1. Pressure = potential force applied / area of ​​force applied

3.2. hρg = h liquid height, ρ = density, g = gravitational acceleration

4. Work

4.1. Magnitude of force x distance the point of application of the force moves in the direction the force acts (7.5N x 8m)

5. Kinetic Energy

5.1. Ek = 1/2mv>2 where m is mass, v is velocity.

6. Accelaration

6.1. rate at which velocity changes with time, in terms of both speed and direction

7. Velocity

7.1. velocity, quantity that designates how fast and in what direction a point is moving.

8. Distance

8.1. the length of the space between two points (d = r t )

9. Friction

9.1. The rough nature of the surfaces is affected. It is confirmed that due to the increase in potential reactions between the two surfaces, the limiting frictional force also increases

10. Newton Laws

10.1. Objects at rest remain at rest until an external unbalanced force is applied, while objects in motion move with uniform velocity.

10.2. The acceleration of an object is inversely proportional to the unbalanced force applied to it and inversely proportional to the mass of the object. f=ma

10.3. Every action has a reaction equal in magnitude but opposite in direction
