Newton’s Laws of MotionNewton’s Laws of Motion

Newton’s First Law-Newton’s First Law- An object at rest will stay at An object at rest will stay at rest and an object in motion will stay in motion in rest and an object in motion will stay in motion in a straight line unless acted upon by an a straight line unless acted upon by an unbalanced forceunbalanced force

Newton’s Second Law-Newton’s Second Law- Force equals mass Force equals mass multiplied by acceleration (f=ma)multiplied by acceleration (f=ma)

Forces Affecting FlightForces Affecting Flight

Thrust- Thrust- Thrust is the force which propels a rocket. Thrust is the force which propels a rocket. Thrust must be greater than the pull of gravity for a Thrust must be greater than the pull of gravity for a rocket to fly upwards.rocket to fly upwards.

Gravity-Gravity- Gravity is the downward force applied to all Gravity is the downward force applied to all objects on earth. More force is required to lift a objects on earth. More force is required to lift a heavy rocket that a light rocket.heavy rocket that a light rocket.

Drag- Drag- Drag is the amount of air resistance or friction Drag is the amount of air resistance or friction on the rocket as it flies. If two rockets of similar size on the rocket as it flies. If two rockets of similar size and weight are launched with the same force, the and weight are launched with the same force, the rocket with lower dray will fly further.rocket with lower dray will fly further.
