Forces & Interactions

What is Newtons first law of motion?

• an object at rest tends to stay at rest and an object in motion tends to stay in motion, unless acted upon by an outside, unbalanced force.
• any two objects exert a gravitational force of attraction on each other
• for every action (force) there is an equal and opposite reaction (force)

What is a force?

• a push or pull
• hitting another object 
• two objects hitting each other
• something that only happens on the moon

What is a balanced force?

• Occurs when an object is not moving
• Occurs when an object is moving
• Occurs when an object is balancing on top of another object 

What is an unbalanced force?

• When an object falls from the top of another object 
• When an object changes position (moves)
• When an object is not moving

What is gravity?

• A force that only happens in space
• A force that moves objects from one place to another
• The force that pulls objects down
• A push or pull

What will happen to a football the harder you kick it?

• The football will stay in place
• The football will go a shorter distance 
• The football will go a greater distance 
• The person kicking the football will fall backwards 

What is Newton's second law of motion?

• An object at rest tends to stay at rest
• the greater the force to an object the great the distance.
• An object in motion tends to stay in motion

What causes static electricity?

• Fire
• A balloon
• Friction
• Something cold

When you rub your feet on a carpet what is happening?

• Electrons build up to create static electricity 
• Nothing happens
• Electrons are released 
• Electrons stay in place

What is an electron?

• Tiny charged particals  
• A band
• Particles that are floating around in the air at all times
