The direction of force of friction is always ______________ to an object's motion.
What is Opposite?
100
This word describes an object's tendency to resist changes in motion.
What is Inertia?
100
This is the force that causes objects to move in a circular path.
What is Centripetal Force?
100
This is Newton's first name.
What is Isaac?
200
You do this when two forces are acting on an object in the same direction.
What is Addition?
200
This is a type of friction when one solid object is dragged across another solid object.
What is Sliding Friction?
200
According to Newton's first law, objects will continue to do what they're already doing unless acted upon by this.
What is an Outside Force?
200
While moving in a circle, and object's inertia will always remain pointed in this direction along its path.
What is a Tangent?
200
The strength of a gravitational force depends on the distance between two objects and this.
What is the Mass of the Objects?
300
This is all the combination of all forces acting on an object.
What is Net Force?
300
This type of friction is a result of the resistance created by liquids and gases.
What is Fluid Friction?
300
This law states that the force acting on an object will be equal to its mass multiplied by its acceleration (F=ma).
What is Newton's Second Law?
300
This is the force which holds both naturally occurring and man-made satellites in their orbits.
What is Gravity?
300
Weight is the measurement of this.
What is Gravitational Force?
400
When the Net Force of an object is 0, we say the forces are...
What is Balanced?
400
This type of friction involves solid objects that move on rounded circular edges.
What is Rolling Friction?
400
Newton's Third law describes the way that momentum is never created or destroyed but only transferred from one object to another. That is why it is often referred to as this.
What is The Law of Conservation of Momentum?
400
The earth's moon is an example of this type of satellite.
What is Naturally Occuring?
400
An elastic force that stretches or pulls on matter.
What is Tension?
500
When net force is anything other than 0, forces are...
What is Unbalanced?
500
This is the friction of stationary or un-moving objects.
What is Static Friction.
500
Daily Double!!!!!!!!!
A boulder with a mass of 200 kg rolls down a hill a speed of 10 m/s and strikes a parked car (which is in neutral). What is the total momentum of both objects AFTER the collision?
500
In order to remain in orbit around the earth, an object's projectile motion must match this.
