Forces
A push or pull.
What is a force?
An object's change in position relative to a reference point.
What is motion?
This man 'discovered' the laws of motion.
Who is Sir Isaac Newton?
A measurement of force, named after a scientist.
What is a newton?
Movement of one object around another in a circular motion.
What is orbit?
The combination of all forces acting on an object.
What is net force?
Tree, mountain, road sign.
What is reference point?
F=m(a)
What is the 2nd Law of Motion?
Kilometers/Hour or Distance/Time
What is speed?
The laws that describe how matter moves in the world.
A force of attraction between objects that is due to their masses.
What is gravity?
The speed of an object in a particular direction.
What is velocity?
For every action there is an equal and opposite reaction.
What is the Third Law of Motion?
Hours or Distance/Speed
What is time?
When a rocket launches.
A force that opposes motion between two surfaces that are in contact. Can be kinetic (moving) or static (not moving).
What is friction?
Motion that follows a curved path that an object follow when projected.
What is projectile motion?
Catching your foot and falling forward is an example of this law of motion.
What is the First Law of Motion?
What is distance?
A tree falling to the ground is an example of this law of motion.
What is the First Law of Motion or Third Law of Motion?
Oil, grease, ball bearings, air.
What are lubricants?
The force that opposes motion of objects through the air.
What is air resistance?
Name two forces that are currently acting on you.
What are gravity and friction?
Distance traveled when running at 8km/h for 4 hours.
What is 32 kilometers?
The rate at which velocity changes over time.
What is acceleration?
