states that any two objects exert an attractive force on one another
What is gravity?
100
Anything thrown or tossed into the air.
What is a projectile?
100
What equation is associated with Newton's 2nd Law?
F=ma
200
Force is equal to _____________x ______________
What is Mass x Acceleration?
200
Describe static friction.
The object is not moving. The frictional force is greater than the force you apply to the object
200
As ___________ increases the force of attraction between the objects increases.
As ___________ increases the force of attraction between the objects decreases.
Mass; distance
200
A specific type of motion that has a vertical and horizontal component to it.
Projectile motion
200
An object has a mass of 75kg and a velocity of 80 m/s. Calculate its momentum.
6000 kg m/s
300
These are the units for force. Which is another way of saying______________
What is a Newton, or Kg m /s/s
300
Describe sliding friction.
The object is moving. The frictional force is less than the force you exert on the object
300
Acceleration due to gravity on earth is always a constant
What is 9.8 m/s^2
300
Parabola, or parabolic arc
What is the shape of a projectiles motion?
300
An object has a momentum of 8000 kg m/s and a velocity of 20 m/s. What is the mass of this object?
400kg
400
This is Newton's second law.
What is – the net force acting on an object causes the object to accelerate in the direction of the net force?
400
Describe rolling friction
The object is in motion. The frictional force is the smallest of all types of friction.
400
Calculate the weight of an object on earth that has a mass of 175 kg.
1715 N
400
An unbalanced force that acts in the direction toward the center of motion
What is centripetal force?
400
An object exerts a force of 550N and has a mass of 50 kg. What is its acceleration?
11 m/s^2
500
This is Newton's 3rd law.
What is – describes action-reaction pairs by stating that every action force has an equal and opposite reaction force?
500
What affects how much friction there is between to objects? (2 things)
Mass of the object. Type of (how rough) surface the object is sliding on.
500
What is the difference between mass and weight?
Mass is the same everywhere you go while the weight of an object depends on mass AND gravity
500
A force that acts opposite the direction of an object's motion.
