Force Flashcards
What is force
A force is something that causes an object to accelerate (a force is something that causes an object to speed up or slow down )
What is force measured by
Force is measured by N - newtons
Types of forces
Pulling
Pushing
Stretching (spring)
Twisting
Gravity
Magnetic
Friction
Electrical
What do you use to measure force
You use a newton meter to measure force
What is gravity
Objects with mass attract others objects with mass (the greater the mass the greater the gravity’)
What is weight
The measure of force of gravity on a object
What is friction
A force that opposes motion
Disadvantages of friction
Slows down veichles
Wasting energy
produces heat energy too high tempetrue for the veichle is dangerous
What is acceleration
Acceleration is how quickly an objects speed or velocity changes
What is mass
Mass is the measurement of the amount of matter in a object
