Y10 Physics

4. is a quantity that has both a magnitude and a direction.
9. is a measurement of mass in motion. It is equal to the mass times the velocity of an object.
12. is the energy an object has due to its motion.
14. is the rate of change in an object's position.
15. the measurement of the change in an object's velocity.
16. is the standard unit of measure for energy and work.
17. states that the greater the mass of an object, the more force it will take to accelerate the object.
18. is the measurement of a push or pull on an object.
21. states that for every action there is an equal and opposite reaction.
22. is a force caused when the mass of physical bodies attract each other.
24. is the resistance of motion when one object rubs against another.

1. any object in motion will continue to move in the same direction and speed unless external forces act on it.
2. is the force of gravity on an object.
3. is the resistance of the object to any change in its motion, including a change in direction.
5. refers to an object's overall change in position. It is a vector quantity.
6. is the energy stored by an object due to its state or position. It is measured in joules.
7. is the ability to do work.
8. is the measurement of how fast on object moves relative to a reference point. It is a scalar quantity measured by distance over time.
10. is a measurement of how much matter is in an object.
11. is the standard unit of measure for force.
13. is a measurement that only measures the magnitude. It does not have direction.
19. is a measurement of the rate at which energy is used. It is calculated by dividing work over time.
20. occurs when any two objects bump into each other.
23. occurs in physics when a force acts on an object to move it some distance. It is equal to the force times the distance and is measured in joules.
