Explanation:

Speed is the rate of change of distance. Example: A car travels 60 kilometers in 1 hour, so its speed is 60 km/h. Inertia is the tendency of an object to resist changes in its state of motion. Example: A book on a table stays at rest until a force (like a hand) moves it. Velocity is speed in a given direction. Example: A plane flying at 500 km/h towards the north has a velocity of 500 km/h north. Newton's 1st Law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Example: A ball rolling on a friction - less surface will keep rolling. Newton's 2nd Law: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object ($F = ma$). Example: Pushing a lighter box (less mass) with the same force as a heavier box will result in a greater acceleration for the lighter box. Newton's 3rd Law: For every action, there is an equal and opposite reaction. Example: When you jump off a boat, the boat moves backward as you move forward.

Answer:

1. Definition: The rate of change of distance. Example: A car travels 60 kilometers in 1 hour, speed is 60 km/h.
2. Definition: The tendency of an object to resist changes in its state of motion. Example: A book on a table stays at rest until moved.
3. Definition: Speed in a given direction. Example: A plane flying at 500 km/h towards the north has a velocity of 500 km/h north.
4. Definition: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Example: A ball rolling on a friction - less surface will keep rolling.
5. Definition: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object ($F = ma$). Example: Pushing a lighter box with the same force as a heavier box gives the lighter box greater acceleration.
6. Definition: For every action, there is an equal and opposite reaction. Example: When you jump off a boat, the boat moves backward as you move forward.
