Newtons Laws of Motion

newtons 1st law of motion states that

an object will remain at rest, or will not change its speed or direction, unless acted on by an unbalanced force.

force is a

vector quantity

types of forces

gravitational, electromagnetic, nuclear

everyday types of forces

normal, resistive, thrust, compression

inertia is

the property of objects that makes them resist changes in their motion. the greater the mass, the more it has

newtons second law of motion

states that the acceleration of an object depends on the size of the net force and the mass of the object

newtons third law of motion

states that for every action, there is an equal and opposite reaction.

forces always occur in

pairs

friction

opposes relative motion of 2 surfaces
