Force & Motion Rev

Science 8

acceleration This is the rate at which velocity changes.
balanced forces This is when forces are combined and there is a zero net force and no change in motion.
motion You can tell that this has occured because an object's position has changed compared to its reference point.
net force This is the resulting force when two or more forces are combined.
speed This is the distance covered in a period of time.
unbalanced forces When forces are combined, this results in a net force and causes a change in motion.
reference point This is an object that seems to stay still.
velocity This is the speed of an object in a given direction.
action force The force that is put on an object.
gravity This is the invisible attaction obetween two objects. Its strength depends on mass and distance.
inertia This is the tendency of objects to resist changes in motion.
momentum This is the measure of an object's motion based on mass and velocity.
weight This measures the force of gravity on an objcet.
reaction force This is the force that an object puts back onto the object putting a force on it.
F = MA This is the formula associtated with Newton's 2nd Law.
Newton's Second Law An example of this law is the harder you kick a soccer ball the farther it will go.
Newton's Third Law An example of this law is when you put a force on a table leg with your toe, the table leg puts a force back on your toe.
Newton's First Law The reason we wear seatbelts can be explained by using this law of motion.
