Newtons Laws of Motion
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"
Newton's 3rd Law states
What is "For every action there is an equal and opposite reaction"
Speed
Scalar Quantity.
Distance / time
Define force
What is "a push or a pull"
Another name for Newton's 1st law of motion
What is "Law of Inertia"
Force is equal to mass x acceleration. State the units of mass and acceleration.
Mass ( g or kg)
Acceleration (m/s2)
Displacement
Vector quantity
Velocity is equal to
Displacement / time
True or False?
Grasshoppers have ears in their bellies
TRUE
What is the formula for Newton's second law
What is "Force = mass x acceleration"
***DAILY DOUBLE***
What is the correct unit of force
What is "Newtons"
Acceleration
Vector Quantity
What is the difference between distance and displacement?
Distance has magnitude only.
Displacement has both magnitude and direction.
Kinetic, Potential, Gravitational, Light, Heat, Sound, Chemical
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"
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"
Scalar Quantity
Force is equal to
mass x acceleration
Which of these examples are compounds?
CO2 ; H2 ; O3 ; NH3
What is "CO2 and NH3"
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"
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"?
Give an example of velocity.
Any answer with magnitude and direction.
For example: 20m/s South
Acceleration is equal to
change in velocity (V final - V initial) / time
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)
