What is friction? | Two surfaces that exert on each other when they rub against each other |
What strength of the force of friction depends on two factors? | How hard the surfaces push together and types of surfaces involved. |
What is static friction? | Friction that acts on objects that are not moving |
What is Sliding friction? | When two solid surfaces slide over each other |
What does newton's first law states? | Objects at rest will remain at rest and a constant moving object will continue moving. |
What is inertia? | Inertia is the tendency of an object to resist a change in motion |
