Across
- 3. the vector sum of forces acting on a particle or object
- 5. a vehicle's capacity to gain speed within a short time
- 6. the resistance that one surface or object encounters when moving over another
- 7. the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a). This means the more mass an object has, the more force you need to accelerate it. And the greater the force, the greater the object's acceleration.
- 9. When two forces acting on an object are equal in size but act in opposite directions
Down
- 1. the SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second, and is equivalent to 100,000 dynes.
- 2. When two forces acting on an object are not equal in size
- 4. When one object exerts a force on a second object, the second one exerts a force on the first that is equal in magnitude and opposite in direction
- 7. strength or energy as an attribute of physical action or movement.
- 8. a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force
