Making contact
I like to move it!
Move it!
It's the arm of the law
100

the speed of an object in a certain direction

velocity

100

forces that you can feel toughing you are

contact forces

100

movement in any direction

motion

100

What is the difference between weight and mass? 

Weight is the measure of the force of gravity on an object. Mass is the amount of matter in an object. 

100

Which takes more energy to move: a carboard box or a large boulder? Explain using one of Newton's laws...

A large boulder because of Newton's second law

200

how far an object moves in a given time

speed

200

An example of a contact force is

friction

kicking a ball

water resistance 

200

Give 5 examples of directions...

North, south, east, west, up, down, left, right, and more!

200

Explain how surface area and air resistance are related to each other? 

The more surface area there is, the more air resistance their is. 

200

What is inertia? Which one of Newton's laws helps explain this concept?

Inertia is the tendency of an object to stay at rest or in motion. Newton's first law explains this. 

300

the tendency of an object to stay at rest or in motion

intertia

300

forces we can not feel touching us, but we know are there

non-contact forces

300

energy that hasn't been released yet

potential energy 

300

What is friction? 

Friction is a force that slows the movement/motion of objects. 

300

How does Newton's third law relate to bouncing a basketball? 

If you push air down on the basketball, the harder you push the higher in the air it goes. If you lightly drop it, it does not bounce as high. 

400

a pull or push of an object

force

400
An example of a non-contact force is 

gravity

magnets

400
energy that is in motion

kinetic energy 

400

What is used to lessen the effect of friction? 

Lubrication can be used to lessen this force

400

Can an objects velocity change while the speed stays the same? 

Yes, Velocity is about speed and direction. Since an object can continue a constant speed while changing direction, then yes the velocity can change while the speed stays the same. 

500

a change in velocity 

acceleration 

500

Are gravity and friction contact or non-contact forces? Explain why you would describe them in that way

gravity- non-contact forces


friction- contact forces

500

On a roller coaster, when does it have the most potential energy and the most kinetic energy? 

Potential- at the top of the hill

kinetic- going down the hill

500

Jane spilled oil on the ground while working on a car, Jack slipped in the oil. What is the oil acting as? 

a lubricant 

500

Can the position of an object change its potential energy? 

Yes, a ball at the top of a hill has more potential energy then on a flat surface.
