Newton’s laws of Motion Video Blogpost
Newton’s first law.
An inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.
In part one the ball didn’t move because there no Fn working on it, so it will stay rest.
In part two when the bus start moving, no force work on the people on the bus so they will feel been puss back.
Newton’s second law
In an inertial reference frame, the vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma.
in the video first I threw a volleyball and a steel plate, as you can see because the mass of the steel plate is higher so when it hit the box the box inverted.
Newton’s third law
When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
When I trow the ball to the wall, because there force on the ball, when it hit the wall it will balance same N force back that make the ball balanced back.
