- Good and bad forces
- Measuring friction
- Forces in collisions
- good and bad forces are the postive and negative effects with friction.
- Friction and Surface
- spring balances measure forces by weighing the mass of an object and converting that to newtons.
- Friction and Mass
- in a collision the vechile stops but our bodies keep moving because of enertia or we don't move and the vechile moves out in front you.the amount of force pushes into both vechiles to crush the crumple zones.
- friction
- the cart will move faster on a smoother surface because there are less and smaller microscopic bumps on the wood for the micrscopic bumps on the wheels. ther are more and larger microscopic bumps for the whells of the cart to catch on in the carpet.
- the heavier an object is the more gravity can act upon the object therefore pushing it down into the microscopic bumbs
- friction is the amount slower and object moves down,up or across a surface due to the roughness and smoothness of the object and the surface it is moving on.
