Question
Inatare i'cesnotes is a push or a pull that one object exerts on is a push or a pull th another object. 2. A force has a size and a(n) a. The length of a force arrow relates to the of the force. b. The direction of a force arrow shows theof the force. 3. The unit of force is the 4. A force can change an object's velocity, which is the and direction of an object, causing B. Types of Forces 1. A(n) force is a push or a pull on one object by another object that is touching it. 2. Contact forces are also called- 3. A(n) forces force is a force that pushes or pulls an object without touching it. 4. Examples of noncontact forces include and gravity C. Frictionn 1. is a contact force that resists the sliding motion between two objects that are touching. 2. The direction of the force of friction is the direction of the motion. 3. surfaces produce greater friction than smoother surfaces do. D. Gravity 1. The noncontact attractive force existing between all objects with mass is 2. The measure of the amount of gravity acting on an object is its as the distance 3. The amount of gravitational force between two objects increases; thus, an astronaut's weight as she or he moves away from Earth into space. 28 Motion, Forces, and Newton's LawsExplanation / Answer
