Year 10 Forces

Year 10 Science - Forces and Motion

TermDefinition
motion A change in an object’s position.
friction A force that occurs when two substances rub together. It will oppose (work against) the movement of an object.
force A push or pull. Measured in newtons (N).
deceleration Decrease in speed of an object.
balanced forces When the forces acting on an object are equal. The speed of the object will stay the same.
distance How far an object has travelled.
speed How fast an object is travelling (calculated as distance travelled / time taken)
time How long a journey takes.
acceleration Increase in speed of an object.
stationary Not moving.
matter The amount of matter or “stuff” in an object. Usually in grams or kilograms.
gravity The force of attraction between objects due to their mass. Greatest for massive objects (e.g. the sun, planets).
weight The force which results from gravity acting on the mass of an object. Measured in newtons (N).
newton The unit by which forces are measured (symbol N).
drag Friction that occurs when an object moves through air or water.
unbalanced forces When the forces acting on an object are not equal. This changes the motion of the object.
