A push or pullThe rate at which something moves in a certain amount of time
Increase in speed of something
Both Speed and Direction(Vector shows direction and Magnitude)
Tendency to do nothing or remain unchanged
When unequal forces cause objects to move
When two equal forces act on an object
Resistance to motion when another object moves across that surface
Amount of energy transferred by a force

Developed “Laws of Motion”Mathematically defined “Gravity”
Autistic, Brilliant Mathematician, Mason
F=maForce= Mass times Acceleration
Acceleration is produced when an unbalanced force acts on a mass
The greater the mass, the greaterthe force is required to move to accelerate the object
An object at rest stays at rest until acted on by an unbalanced external force
An object at in motion stays in motion until acted on by an unbalanced external force
For every action there is and equal and opposite reaction

Force equals mass times acceleration
F=ma so,...42kg x 25 m/s=
10.5 N
F=ma so,…..5 divided into 20 Acceleration =4m/s
F=ma so,…F= 300kg x4 m/s2
F= 1200 N
Rocket’ thrust expels atoms in one direction creating unbalanced forces, and the rockets' atoms move in the opposite direction
When you create unbalanced forces by pushing on the atoms in the wall, you are repelled in the opposite direction and move away from the wall.
When I let go of the balloon, the unbalanced forces would move air in one direction, and the balloon’s mass in the opposite direction
Constant speed(Never changes speed)
Object not moving(Time is changing, but distance is not)
Object turns around and heads back to start location
Object is accelerating and getting faster!
