Object at rest stays at rest, object in motion stays in motion unless acted on my external force. Person was traveling at a speed with the car. Car comes to a stop, but inertia keeps the person moving. Seatbelt stops you at the external force.

F = ma a = F/m F m a a = 50 N/ 5kg a = 10 m/s2

W m g force gravity acceleration 9.8 Newtons 𝑾𝒆𝒊𝒈𝒉𝒕=𝒎𝒂𝒔𝒔 ∙𝒈𝒓𝒂𝒗𝒊𝒕𝒚 Weight is a type of _______________________. It is essentially the force of __________________ pulling on a mass. Your weight is your mass multiplied by the __________________________ due to gravity on Earth, which is _____________________m/s2. Weight is measured like all forces, in ______________________. We find Weight with the following formula: gravity acceleration 9.8 Newtons 𝑾𝒆𝒊𝒈𝒉𝒕=𝒎𝒂𝒔𝒔 ∙𝒈𝒓𝒂𝒗𝒊𝒕𝒚 W m g

When you kick an object (ball or furniture), the object pushes back with equal and opposite force. Don’t you feel it??
