Contact And Non Contact Forces Flashcards
Force is a …. quantity
Vector!
Vector quantities have
Magnitude(or size) and a direction,like force,velocity.
Some have a force but no direction,what r these
Scalar quantities,like mass speed or distance
Vectors r usually represented by an arrow,the length of the arrow represents the ….. and direction represents the……
Size (or magnitude),direction of quantity,
Forces can be a contact or ….. ….. force
Non cantact force
A force is a ….. or …..
Push or pull
Forces are caused by objects …… w eachother
Interacting w eachother
When two objects have to be touching fot he force to act this is a
Contacts force
If two objects dont have to be touching this is a
Non contact force
Non contacts force is
Magnetic force,gravitational force,electrostatic force
Contact force is
Friction,air resistance,tension,normal contact force
An interaction pair is when
Two objects interact , a fprce is produced on both objects,equal in size but oppisite directions
