Newton's Second Law
The forces acting on your sled
What is gravity, friction, and air resistance?
Newton's first law
What is 'An object at rest will stay at rest and an object in motion will stay in motion in a straight line and at uniform speed unless an acted upon by an unbalanced force.
If I take a feather and a 200 lbs person into space, will they weigh the same and will they have the same mass?
The feather and person will weight same because they will be weightless but their masses will be different.
They landed at the same time.
What is the result of Galileo's experiment with falling objects of different masses?
m=F/a
What is solving for mass using Newton's sEcond Law?
a box is pulled 4N to the right and pulled 6N and 2 N to the left.
What is a net force of 4 N to the left?
Applying one of Newton's law to your lives.
