accelerating force is more than resistance. As velocity increases resistance builds up - reduces acceleration. Resistance force = accelerating force. TERMINAL VELOCITY

Terminal velocity DEPENDS ON
shape & area. MOON (no air) brick & feathers fall simultaneously. EARTH (air resistance) brick & feathers fall at different speeds. TERMINAL VELOCITY depends on DRAG compared to WEIGHT.

FIRST LAW OF MOTION
BALANCED FORCES = NO CHANGE in VELOCITY (forces balanced - 0 resultant force)
3 of 6
SECOND LAW OF MOTION
If there is an UNBALANCED FORCE, an object will ACCELERATE in that direction.

MOTION (3 points)
The BIGGER the FORCE the GREATER the ACCELERATION/DECELERATION. The bigger the MASS, the SMALLER THE ACCELERATION. For a BIG mass to ACCELERATE AS FAST as a SMALL MASS it needs a BIGGER force
