s2w1 Newton's third law and Momentum

A BIG 18 wheeler tractor trailer and a SMALL Mini Cooper are both driving alongside each other on a highway, and both have to come to a stop because of an accident up ahead.

1

Which vehicle has more inertia as they come to a stop?

1

Explain WHY your chosen vehicle has more inertia and what that means as each vehicle comes to a stop. Be sure to focus on explaining INERTIA in your answer.

When forces are balanced, they

1

A combination of all the forces acting on an object is called

1

When the net force on an object is zero, the object's motion will

1

To find the net force on an object:

1

If you are pushing a box toward your friend with a force of 20 N, and your friend is pushing the box toward you with a force of 30 N, what will happen to the box?

1

If an object is moving forward with a constant velocity of 12m/s, what kind of forces are acting on the object?

1

If an object is stationary, what kind of forces are acting on it?

1

For a given acceleration, the mass of an object is _________________ the force of that object.

1

For a given resultant force, the acceleration of an object is _________________ the mass of that object.

1

If you hit a wall with a stick with 250N of force how much force does the wall put on the stick?

1

Explain why when two objects collide one object moves faster than the other, and yet Newton's 3rd law says the forces on each object are the same.

Which of the following is the kind of force pair described by the video?

Read through the first 6 pages of the chapter 5: momentum. Do you have any questions?

1

is momentum a scalar or a vector?

4

Momentum can be defined as " _______ in _______ "

John and Jane put the same amount of force on their equal size/equal mass boxes, which moves across the ice rink in their perfect physics land. John pushes for 3 minutes, while Jane pushes for 6 minutes. Which box is going faster after 10 minutes?

1

Two vikings throw their glasses down with the same amount of force. They have the same momentum right before they hit the ground. One viking is on tile, his glass breaks. The other viking is on carpet, his glass does not break. Explain why the second glass doesn't break in terms of force, momentum or impulse.

A ball falls. at a certain distance A above the ground, it has a velocity of .3m/s down. Once it hits the floor and bounces, at point B above the ground it reaches a velocity of .3m/s up. Does it have the same momentum at point A and B? explain why.
