Final Jeopardy

Force and Motion

$100 Question – Types of Forces

All forces are either a _________________ ora ________________.

$100 Answer - Types of Forces

push or pull

$200 Question - Types of Forces

$200 Answer - Types of Forces

D - gravity

$300 Question - Types of Forces

$300 Answer - Types of Forces

A – they will push away from each other (repel).

$400 Question - Types of Forces

$400 Answer - Types of Forces

B – acts when two objects rub against each other.

$500 Question - Types of Forces

$500 Answer - Types of Forces

B – the moon moves (revolves) around Earth.

$100 Question – Motion of Objects

$100 Answer - Motion of Objects

B – the forces acting on the object.

$200 Question - Motion of Objects

$200 Answer - Motion of Objects

C – change the object’s mass.

$300 Question - Motion of Objects

$300 Answer - Motion of Objects

C – 25 kilometers

$400 Question - Motion of Objects

$400 Answer - Motion of Objects

A – the ball’s direction will change.

$500 Question - Motion of Objects

How do you know?

$500 Answer - Motion of Objects

F – the box filled with feathers. Since all the boxes are being pushed with the same force, the box with the least mass will have the greatest change in its rate of motion (speed).

$100 Question – Motion of Objects 2

$100 Answer - Motion of Objects 2

H – its motion does not change.

If the object was already sitting still, it will remain still. If the object was already moving andthen two balanced forces acted on oppositesides, the object would continue to move as itwas moving already.

$200 Question - Balanced & Unbalanced Forces

$200 Answer - Motion of Objects 2

C – the forces acting on the object are balanced.

Remember, when the forces acting on an objectare balanced, the object does not move. A stronger force must be acting on one side (unbalanced forces) for the object to move.

$300 Question - Motion of Objects 2

What would most likely happen if another student was added to either side of the rope? Why?

$300 Answer - Motion of Objects 2

The rope would most likely move in the directionwhich the student was added. This is becausethe forces will become unbalanced, with oneside having a greater force than the other.

$400 Question - Motion of Objects 2

What would most likely happen if another student was added to the right

side of the rope? Why?

$400 Answer - Motion of Objects 2

If another student was added to the right side ofthe rope, the forces would most likely becomebalanced, or equal, which would cause the ropeto stay in the same place.

…until one side of students gets more tired than the other. When that happens, their force will be weaker, and the forces will be unbalanced.

$500 Question - Motion of Objects 2

$500 Answer - Motion of Objects 2

D – the less effect a force will have on the object’s motion.

$100 Question – More About Friction

$100 Answer - More About Friction

D – a moving object slows down.

$200 Question - More About Friction

$200 Answer - More About Friction

A – it only affects objects that are touching.

$300 Question - More About Friction

$300 Answer - More About Friction

H – air resistance.

Air resistance is like friction between the air anda moving object.

$400 Question - More About Friction

$400 Answer - More About Friction

C - grease

$500 Question - More About Friction

What is a lubricant and how does it relate to friction? Give an example.

$500 Answer – More about Friction

A lubricant is a substance that decreases theamount of friction between objects. An examplewould be oil. If oil was spilled on a smooth floor,the floor would become much more slippery because the oil, acting as a lubricant, would decrease the friction between the floor and people’s shoes.

$100 Question – Wild Card

$100 Answer – Wild Card

D – how much matter makes up an object.

$200 Question – Wild Card

$200 Answer – Wild Card

B – they have a north and south pole.

$300 Question – Wild Card

$300 Answer – Wild Card

D – slower. Since the same amount of force was used, the ball with the greater mass will travel slower andless distance.

$400 Question – Wild Card

$400 Answer – Wild Card

D - fast

$500 Question – Wild Card

$500 Answer – Wild card

C – pushing the box with a greater force.

This could make the box move up the ramp faster, but it would not decrease the amount of friction between the box and the ramp.
