Sure, here are the key formulas and their terms from the lesson on laws of motion:

1. Newton's First Law of Motion:
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. This is also known as the Law of Inertia.

2. Newton's Second Law of Motion:
The force acting on an object is equal to the mass of that object times its acceleration. This is often written as F = ma.
- F is the force applied on the object.
- m is the mass of the object.
- a is the acceleration of the object.

3. Newton's Third Law of Motion:
For every action, there is an equal and opposite reaction.

4. The formula for calculating momentum (p) is: p = mv
- p is the momentum.
- m is the mass of the object.
- v is the velocity of the object.

5. The formula for calculating kinetic energy (KE) is: KE = 1/2 mv^2
- KE is the kinetic energy.
- m is the mass of the object.
- v is the velocity of the object.

6. The formula for calculating gravitational potential energy (PE) is: PE = mgh
- PE is the potential energy.
- m is the mass of the object.
- g is the acceleration due to gravity.
- h is the height above the ground.

7. The formula for calculating work done (W) is: W = Fd
- W is the work done.
- F is the force applied.
- d is the distance over which the force is applied.

8. The formula for calculating power (P) is: P = W/t
- P is the power.
- W is the work done.
- t is the time taken to do the work.

9. The formula for calculating impulse (J) is: J = Ft
- J is the impulse.
- F is the force applied.
- t is the time over which the force is applied.

10. The principle of conservation of momentum states that the total momentum before an event must be equal to the total momentum after the event. This can be written as: m1u1 + m2u2 = m1v1 + m2v2
- m1 and m2 are the masses of the two objects.
- u1 and u2 are the initial velocities of the two objects.
- v1 and v2 are the final velocities of the two objects.
