newtons first law u1

distance how far you traveled between two positions. it is a scalar quanity
displacement change in positions the strait line distance between your starting and ending position
scalar Quantity that only requires magnitude
vector Quantity that requires both magnitude and directions
speed how fast something is moving its scalar quantity
velocity rate at witch positions change its a vector quanity
newtons first law an object at rest stays at rest and an object in motion stays in motion until its acted upon by an unballenced force
mass measure amount an object contains
inertia the resistance an object has to change its motion
force any push or pull that causes change in motion
net force the combination of all the forces on an object
balanced force when the net force in both the horizontal and vertical is 0.N these cause the motion to stay unchanged
unbalanced force when the net force in both the horizontal and vertical is not 0.N these cause the motion to change
gravitational force A non-contact force between two objects that is most apparent close to a large object, such as a planet, The direction of the force is general towards the center of the other object. Eg. Towards the center of the earth.
applied force the support force exerted upon an object that is in contact with another stable object. It is in the direction of the push or pull.
normal force A contact force that is exerted by a surface against an object that is pressing against the surface. It is perpendicular to the surface and present whenever atoms are being “crunched”. AKA “crunchy force”
