Force and motion

5. The quantity of motion in an object, calculated as the product of its mass and velocity (8)
7. The acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to its mass (three words) (7)
10. A measure of how difficult it is to change the velocity of an object (7)
11. The force exerted on an object due to gravity (6)
13. The force that pulls objects toward the center of the Earth (6)
14. The force exerted by a spring when it is compressed or stretched (6)
15. The speed of an object in a particular direction (8)

1. The rate at which an object's velocity changes over time (11)
2. The force that is transmitted through a string, rope, cable, or any other type of flexible connector (7)
3. The force that acts between two surfaces in contact and opposes the motion or tendency of such motion (5)
4. force The overall force acting on an object when all the individual forces acting on it are added together (10)
6. The resistance of any physical object to any change in its state of motion (7)
8. The force that opposes the motion of an object through a fluid (liquid or gas) (7)
9. The force exerted by a surface as an object moves across it or makes contact with it (7)
12. Velocity The constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration (14)
