Motion and force
| Question | Answer | null | null |
|---|---|---|---|
| An Object Is In Motion If: | Its position changes when compared to another object | ||
| What is a reference point? | A reference point is a place or object used for comparison to determine whether something is in motion | ||
| Why is motion relative | motion is determined by a reference point that can change | ||
| How does force affect motion | It can pull or push another object to make it speed up slow down and change direction | ||
| How was the force described | By its strength and the direction in which it acts | ||
| In an image what can the direction and strength of a force to be represented by | An arrow | ||
| What about an arrow dictates the strength of a force | The length | ||
| What is the units of strength for a force | A Newton after sir Isaac newton | ||
| What are two types of forces | Noncontact And contact Forces | ||
| Example of a contact force | Friction | ||
| Three examples of a noncontact force | Magnetism, electrical, gravity | ||
| What is balanced force | Balance force is when two forces acting on an object are equal in strength and opposite in direction | ||
| What is an unbalanced force | Two forces unequal in Strength manipulate an object | ||
| What is the net force | combination of all unbalanced forces on the object |
