Question 25

The three laws of motion are

Answer 25

Law of Inertia, Law of Acceleration, and Law of Interaction

Question 26

This is the 2nd law of motion where the total force acting on an object is not zero.

Answer 26

Law of Acceleration

Question 27

Law of acceleration is directly proportional to ------- and inversely proportional to -----

Answer 27

net force, mass

Question 28

This is the 1st law of motion where it is the tendency of an object to resist change in its state of motion. An object at rest tends to remain at rest. An object in motion will remain in motion with constant velocity unless acted by an external force

Answer 34

Law of Conservation of Mass

Question 35

states that this cannot be created nor be destroyed, it will only transfer from one form to another form. The total amount of this in a closed system remain constant over time

Answer 35

Law of Conservation of Energy

Question 36

It is the total potential energy and kinetic energy. Loss of kinetic energy is gain in potential energy

Answer 36

Law of Conservation of Mechanical Energy

Question 37

It is moving object, increasing in speed

Answer 37

Kinetic Energy

Question 38

Stored energy increase in elevation increase in potential energy

Answer 38

Potential Energy

Question 39

It is mass in motion, when an object is moving then it has momentum

Answer 39

Conservation of Momentum
