Newtons 1st Law
An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.
Newtons 2nd Law
The acceleration of an object depends on the force applied and the object’s mass.
Newtons 3rd law
for every action (force) in nature there is an equal and opposite reaction
If a car crashes how does newtons first law apply
When a car crashes, Newton’s First Law applies. The car stops suddenly, but the people inside keep moving forward because of inertia. This is because objects in motion stay in motion unless acted on by an unbalanced force — like a seatbelt or airbag.
explain what is meant by acceleration due to gravity and provide it’s approximate value on Earth
Acceleration due to gravity is the rate at which objects fall towards Earth because of its gravitational pull. On Earth, it is approximately 9.8 m/s², meaning an object’s speed increases by 9.8 metres per second every second as it falls
