Newton's First and Second Laws

________ first law says that a resultant force is needed to make something start moving, speed up or slow down.

________ is also inversely proportional to the mass of the object- so an object with a larger mass will ________ less than one with a smaller mass.

A(n) ________ will always produce acceleration in the direction of the force.

The velocity will only change if theres a(n) ________ actin on the object.

________ is proportional to the resultant force.

starting, stopping, speeding up, slowing down and changing direction

force is needed to__

non-zero resultant force will always produce_______

resultant force equation:__________

large forces are needed to produce_____
