Answer hidden
What type of forces happen when one object directly touches another object?
Answer hidden
A force is the push or pull on an object which happens when one object does something to another object. Forces can make something speed up, slow down, stop, stay in place, or change shapes. There are many kinds of forces, but the two main categories are contact and non-contact forces. Contact Forces happen when one object directly touches another object. When an object moves across a surface, it causes ______.
Answer hidden
Air resistance force is an example of a non-contact force. Which force is responsible for making a parachute land more slowly by filling it with ______? Contact forces happen when one object directly touches another object. When an object moves across a surface, it causes friction. Frictional force is the effort needed to move two objects past each other.
