Newton's 1st and 2nd Laws of Motion. Each will have 4 answers.

Groups:

(a) Newtons 1st Law of Motion

,

(b) Newton's 2nd Law of Motion

• Law of acceleration

• An object in motion tends to stay in motion unless acted upon by an outside force

• F = ma

• More massive objects require more force to move or stop (accelerate)

• An object at rest tends to stay at rest unless acted up on by an outside force

• Law of Inertia

• More massive objects require more force to change direction (accelerate)

• Objects will maintain the same velocity (speed, direction) until an outside force changes it
