What is Newtons first law of motion?
Law of Inertia states that an object that is at rest will stay at rest and an object that is moving will keep moving with constant speed in same direction unless an external force acts on that object.
What is Inertia?
Resistance to a change in motion
What is newtons second law?
Law of momentum states that the forces acting on an object is directly proportional to the mass of the object and acceleration produced. F=ma 
What is newtons third law?
Law of action and reaction states that every action there is an equal and opposite reaction
What is meant by velocity?
Measures how fast an object moves at a particular direction.
What is meant by acceleration?
The change in velocity over time.
What is the formula linking velocity, acceleration and time?
$a =$ $∆ v/t$
What is the magnitude of the acceleration due to gravity?
9.8 m/s^2
