You push on a crate with a force of 10 N to the right, and your friend pushes on the crate with a force of 25 N to the left. Describe and explain the motion of the crate.
You push a heavy box. At first it doesn't move. You push harder, and it finally starts to move, but you still have to exert a constant force to keep it moving across the room. Explain why.
Can an object still be in motion if the net force acting on it is zero? Explain.
An object at rest will remain at rest and an object in motion will stay in motion unless acted upon by an unbalanced force.
An object’s acceleration depends on its mass and the net force acting on it. (F = ma)
When one object applies a force on a second object, the second object applies a force on the first object that is equal and opposite.
Using one or more of Newton’s laws, explain why you fall forward when you trip on a crack.
Using Newton’s third law of motion, explain how you are able to walk forward.
Using one or more of Newton’s laws, explain why it is necessary to wear a seat belt to hold you in place if your car that stops suddenly?
