Science flashcards

Distance How far you travel between 2 points. Its always positive and a scalar quantity
Displacement Change in position. It is the straight line distance between your starting position and ending position. It is equal to find position minus initial position. It can be positive or negative.
Scalar Quantity that only requires magnitude ( how big ).
Vector Quantity that both require magnitude ( how big ) and directions.
Speed How fast something is going. It is equal to distance divided by time. It is a scalar quantity
Velocity Rate at which positions change. It is equal to displacement divided by time. It is a vector quantity.
Newton's First law AKA the law of inertia. An object in motion will stay in motion. An object at rest will stay at rest, unless acted upon by a force.
Mass A measure of the amount of matter an object contains
Inertia The resistance of an object has to change in motion
Force any push or pull (interaction) that can cause a change in motion
Net force The combination of all forces on an object
Balanced force When the net force in both horizontal and vertical directions is 0 N. These cause motion to remain unchanged
Unbalanced force When the net force in both the horizontal and the vertical is not 0 N. These cause motion to change
Gravitational force/ weight Fg A non-contact force between 2 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 an object . Eg. Towards the center of the earth.
