Across
- 3. is force acting in the opposite direction.
- 6. force a force that changes the position, speed or direction of the object to which it is applied.
- 7. is the resistance of any physical object to any change in its velocity.
- 9. the resistance that one surface or object encounters when moving over another.
Down
- 1. strength or energy as an attribute of physical action or movement.
- 2. force vector sum of forces acting on a particle or body.
- 4. Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied
- 5. three law of motion
- 8. force acting in one direction.
- 9. Newton's second law of motion describes the relationship between an object's mass and the amount of force needed to accelerate it.
