- 7. The change in an object's position with respect to time and a frame of reference.
- 9. The tendency of an object to resist changes in its state of motion. Objects at rest stay at rest, and objects in motion stay in motion unless acted upon by an external force.
- 10. The SI unit of force, named after Sir Isaac Newton. One newton is the force needed to accelerate a one-kilogram mass by one meter per second squared.
- 11. A measure of the amount of matter in an object. It is typically measured in kilograms or grams.
- 12. The force exerted by gravity on an object. It is calculated as the mass of the object multiplied by the acceleration due to gravity.
Down
- 1. A push or pull upon an object resulting from its interaction with another object, often causing a change in motion.
- 2. The speed of an object in a specific direction. It is a vector quantity, meaning it includes both magnitude and direction.
- 3. The path along which something moves, points, or faces.
- 4. A force of attraction between two masses. On Earth, it gives weight to physical objects and causes objects to fall toward the ground.
- 5. of Reference: A set of criteria or stated values in relation to which measurements or judgments can be made. In physics, it refers to a coordinate system or viewpoint used to describe motion.
- 6. The rate of change of velocity of an object. It is calculated as the change in velocity divided by the time taken.
- 8. Force: The overall force acting on an object when all the forces are combined. It determines the object’s acceleration.
