Contact Nd Non-contact Forces Flashcards
What is a force
A force is a push or pull that acts on an object
How are forces caused
Forces are caused by objects interacting with eachother
What are the two types of forces
Contact, Non-contact
What is a contact force
Friction, air resistance, tension, normal contact force
What is a non-contact force
Gravitational force, magnetic force, electrostatic force
What is a interaction pair
When two objects interact, a force is produced on both objects. The forces on the two objects are equal in size but act in opposite directions
What is vector quantity
Vector quantities are: force, velocity, displacement, accelaration
What is scalar quantity
Scalar quantities are : speed, distance, mass, tempurature, time
What are vectors usually represented by
Vectors are usually represented as arrows
