Question | Answer |
Force is a | Push or pull that acts on an object and make it speed up or slow down. |
A force can also | cause an object to change direction |
Gravity | is the force that exists on the earth between 2 objects |
Gravity also | pulls an object down from floating when you throw it into the air or when u jump |
Magnetism | is a force that exists when a magnetic field is present. It force acts on certain metals such as Iron and Steel |
Friction | Is a force that resists the movement of one surface past another surface |
Friction also depends on the | mass of the object |
Air Friction | Works with gravity to slow the upward motion of the rocket when u throw it up in the air |
Effects of friction | You can walk, turn, and push. Moving Parts in a machine work better with less friction between the parts |
Reducing Friction | You use oil in a car to reduce friction and grease on a bikes chain |
Lubricant | is any substance that reduces friction and helps moving parts move more friction |
Static Friction | A part of friction that makes something straight like a desk so objects can stay on it |
Sliding Friction | Like a toy car going on a carpet and the carpet will slow it down |
Rolling Friction | Like putting objects on a cart to move it quicker |
Fluid Friction | Is air resistance so it affects an object when falling normal paper floats while when crumpled it moves faster |
