A push and pull of an object imteracting with another object

FORCE

Newtons

2 types of forces

Contact and Non-contact Force

A type of force that needs the objects to touch for the the force to work.

Contact Force

CF

A type of force that can happen without the objects touching.

Non-Contact Force

NCF

Push and pull exerted by a magnet.

Magnet Force

Magnet

The force that attracts objects towards the earth’s center.

Gravitational Force

Unit is m/s^2

The force that exists betweem all charged particles.

Electrostatic Force

Lightning

Types of Contact force.

Applied,Normal,Frictional,Air Resistence,Tensional,and Spring Force.

ANFATS

A force which is applied to an object by another or by a person.

Applied Force

Reffered to as pressing force and is always directed towards the object and acts perpendicularly.

Normal Force

Opposes the motion of object.

Frictional Force

A special type of force.

Air Resistance Force

Transmitted thorugh a string, rope, or wire when pulled tight by force acting at each end.

Tensional force

Exerted by a spring upon any object which is attracted to it.

Spring force

Equal forces acting in opposite directions thus having Zero net force.

Balanced force

Has nonzero net force and produces acceleration.

Unbalanced force.

A measurement of an objects inertia.

Mass

Who discovered the three laws of motion?

Sir Isaac Newton

What are the three laws of motion?

Law of Inertia,Acceleration, and Interaction

States that an object at rest remains at rest and an object in constant motion remains to be in that state of motion.

Law of inertia

3 Formulas used in Law of Inertia.

g=m/w


w=m x g


m = w/g

States that the direction of the net force and acceleration are the same, and both are directly related while acceleration and mass are inversely related.

Law of Acceleration

A

3 formulas used in law of acceleration.

F = ma


A = f/m


M = f/a

Unit of Force and weight

Newtons or N

Unit od gravity and acceleration

m/s^2

Unit of mass

Kilogram or kg
