Forces And Motion Flashcards
What is a force
A force is an interaction between two objects in the form of a push or pull that causes a change in speed,direction or shape
What happens when there is a resultant force
It will speed up or slow down
What happens when there is not an resultant force
Then the object was stationary
What would happen without gravity
We would all be floating around
When two surfaces are rubbing together it creates
Friction is created
When there is friction what else is produced
Heat is also produced with friction
What direction does the force of friction go to
It goes the opposite way of something moving
What is another type of friction in the air
The other type of friction is called air resistance
Objects that are designed to go through the air are called
Streamlined and aerodynamic
What is friction used on
It’s used on tyres to grab the vehicles grip
What liquids do you use to not affect the machine
You use lubricant to not affect the machine
In science what do you use to calculate speed
You use meters per second
What does speed =
Distance / time
What does pressure =
Force / area
