Forces Flashcards
What is decanting
A simple method of seperation where the mixture is left long enough so that a sedimation is formed at bottom of the container. The liquid is then poured carefully into another container.
Whats one way to look for forces?🤔
Look out for movement.
Motion comes from something being punched against another
What is Newton’s third law
Every action has an equal and opposite reaction.
What is friction
Friction is a force that slows everything that is moving. More friction=less speed
Give an example of a balanced force
Tug-of-war When both teams are as strong as each other the force is balanced
what is a force?
a force is anything that can effect speed, direction and shape
what is force measured in?
newtons
what is a contact force?
a visible force that has an effect on something eg:friction
what is non-contact force?
an invisible force that has an effect on something eg:gravity
what is gravitational force?
a force that attracts any object with mass
how is friction formed?
2 surfaces rubbing against eachother
what is friction?
a force that opposes motion
what is a lubricant?
a substance used to reduce friction
Whats newtons 1st law?🤔
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force..
Are forces good
