- 3. Sum of all forces acting upon an object.
- 5. a force that causes change in motion.
- 7. A change in velocity over a period of time.
- 8. A physics equation known commonly under Newton's Second Law of Motion. It states that force is equal to mass multiplied by acceleration.
Down
- 1. when two surfaces make contact and form resistance.
- 2. Unit of force.
- 4. The principle of inertia states that a body at rest will remain at rest and a body in motion will continue moving with a constant speed unless acted upon by an external force non zero force.
- 6. Defined in the Newton's 3rd Law
