Force por Mind Map: Force

1. Basics

1.1. What is force

1.1.1. Push or pull

1.1.2. Described by

1.1.2.1. Strength

1.1.2.2. Direction

1.2. What is a Newton

1.2.1. SI unit used in measuring the strength of force

1.2.2. It was named after the English scientist Isaac Newton

1.3. Kinds on forces

1.3.1. Balanced forces

1.3.1.1. Balanced forces acting on an object do not change the objects motion

1.3.2. Unbalanced forces

1.3.2.1. Unbalanced forces acting on an object result in a net force and cause in objects motion

2. Friction and Gravity

2.1. Friction

2.1.1. Strength of a force of a object rubbing on to another

2.1.2. Types of friction

2.1.2.1. Static friction

2.1.2.2. Sliding friction

2.1.2.3. Rolling friction

2.1.2.4. Fluid friction

2.2. Gravity

2.2.1. Universal gravity

2.2.1.1. Gravity is everywhere not just on earshot is the force that keeps the moo orbiting around earth. It is also the force that keeps the solar system going on.

2.2.2. Factors affecting Gravity

2.2.2.1. Two factors affect the gravitational attraction between objects mass and distance.

2.2.3. Weight and mass

2.2.3.1. Mass is the measurement of the amount oh matter in an object; weight is a measure of gravitation force exerted on a object.

3. Laws of motion

3.1. 3 important people

3.1.1. Aristotle

3.1.1.1. Naturally

3.1.1.1.1. Not gravity, not friction, free fall

3.1.2. Galileo

3.1.2.1. If an object is in motion it will keep moving until it is forced to stop either by a barrier or by force.

3.1.2.2. Gravity, friction (Air resistance)

3.1.3. Sir Isaac Newton

3.1.3.1. The first law of motion

3.1.3.1.1. Newtons first law of motion states that an object will rest remain at rest and an object moving at velocity will keep moving unless it is a unbalanced force.

3.1.3.2. The third law of motion

3.1.3.2.1. Newtons third law of motion states that if one object exerts a force on another then the second object exerts force of equal strength in the opposite direction on the first object.

3.1.3.3. At the age of 22, is when the apple fell of Isaacs head and that is when he confirmed gravity exists.

4. Momentum

4.1. Momentum is the quantity of motion and can be determined by multiplying the objects mass by its velocity

4.1.1. Momentum= Mass x Velocity

4.1.1.1. Momentum= Mass x Velocity

4.2. Newtons third law of motion states that if one object exerts a force on another then the second object exerts force of equal strength in the opposite direction on the first object.
