newtons first law u1
Term | Definition |
---|---|
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” |
