Mad Science ( Forces )

Today in mad science I would be giving you a quick definitions of words in the letter groups a-z under the topic forces.

A-E

AIR RESISTANCE is a force that acts against any object moving through the air.

BALANCED FORCES are opposing forces that cancel each other out.

EARTH'S GRAVITY is the force of attraction that pulls objects towards the center of the Earth.

F-J

A FORCE is a push or pull measured in Newtons.

FRICTION is a force that occurs between two surfaces rubbing against each other.

GRAVITY is the force of attraction between any two objects that have *mass.

K-O

MASS is the amount of matter an object is made up off measured in kilograms.

NEWTON is the unit used to measure forces.

P-T

RESULTANT FORCE is a single force that has the same effect as all the forces acting on an object added together.

SATELLITES are any objects orbiting another objects.

STREAMLINED is a smooth shape designed to remove drag.

THRUST is a force that pushes an object forward.

U-Z

UNBALANCED FORCES are forces acting on an object that changes its speed, direction or shape.

UPTHRUST is a force that pushes an object upwards.

WEIGHT is the force caused by gravity acting on an object, measured in Newtons.
