Newtons Laws of Motion

100

Finish the phrase: "An object in motion stays in motion and...

What is "an object at rest stays at rest unless acted upon by an equal and opposite force"

200

Another name for Newton's 1st law of motion

What is "Law of Inertia"

300

What is the formula for Newton's second law

What is "Force = mass x acceleration"

400

This is an example of which of Newton's laws?  If you kicked a ball in space, it would keep going forever, because there is no gravity, friction or air resistance going against it.

What is "Newton's 1st law or the law of inertia"

500

This is an example of which of Newton's laws?  You are driving a car and hit a tree. The car comes to a stop, but you body keeps moving forward.

What is "Newtons 1st Law or Law of Inertia"

Newtons Laws of Motion... again

100

Newton's 3rd Law states

What is "For every action there is an equal and opposite reaction"

200

Force is equal to mass x acceleration. State the units of mass and acceleration.

Mass ( g or kg)

Acceleration (m/s2)

300

***DAILY DOUBLE***

What is the correct unit of force

What is "Newtons"

400

This is an example of which of Newton's Laws?  When you dive off a diving board, you push down on the springboard.  The board springs back and forces you into the air.

What is "Newton's third law or the law of action/reaction"

500

While repairing the Hubble Telescope, which is in space, an astronaut turns a screwdriver clockwise. What direction will the astronaut turn?

What is "counter-clockwise"?

Vector or scalar Quantity?

100

Speed

Scalar Quantity.

200

Displacement

Vector quantity

300

Acceleration

Vector Quantity

400

Distance

Scalar Quantity

500

Give an example of velocity.

Any answer with magnitude and direction. 

For example: 20m/s South

Motion calculations

100

Speed is equal to:

Distance / time

200

Velocity is equal to 

Displacement / time

300

What is the difference between distance and displacement?

Distance has magnitude only.

Displacement has both magnitude and direction. 

400

Force is equal to 

mass x acceleration

500

Acceleration is equal to 

change in velocity (V final - V initial) / time

Random Science

100

Define force

What is "a push or a pull"

200

True or False?

Grasshoppers have ears in their bellies

TRUE

300

Name 3 types of Energy.

Kinetic, Potential, Gravitational, Light, Heat, Sound, Chemical

400

Which of these examples are compounds?

CO₂  ;   H_{2   ;}    O₃   ;  NH₃

What is "CO₂  and NH₃"

500

What are the two types of Forces we studied and give one example of each. 

Contact Force (Tension, friction, air resistance etc.)

Non-contact force (Gravitational, electromagnetic, magnetic)
