PBHS Acceleration

Acceleration due to gravity

QuestionAnswer
A net force causes a mass to ___ accelerate
In a = F/m, acceleration is directly proportional to __ (net) force
a = F/m or F = ma is a formula developed by this man Isaac Newton
a = F/m or F = ma is the formula representing which law of motion Newton's 2nd Law of Motion
A falling object reaches terminal velocity when these two forces are balanced weight(gravity on an object) and air resistance
Weight is a ___ force
In SI, all forces are measured in ___ newtons (N)
Constant velocity results when forces are balanced (no net force)
The constant velocity reached by a falling object when forces acting on it are balanced is called ___ terminal velocity
The amount of gravity any object has is due to the object's amount of ___ mass
In a = F/m, acceleration is inversely proportional to ___ mass
The amount of air resistance acting upon an object is based on the object's ___ surface area
When a falling object's weight is greater than the force of air resistance the object will be accelerating by speeding up
When a falling object's weight is less than the force of air resistance acting on it, it will accelerate by slowing down
In the absence of air, all objects fall at the ___ same acceleration or same rate
This force opposes all motion. friction
The force of gravity on Earth causes an acceleration rate of ___ 9.8 m/s squared
Adding all of the forces acting upon an object together finds the ___ force. net (force)
Moving at a constant velocity requires forces that are ____ balanced (forces)
When all of the forces acting on a body add up to zero, there is no __ acceleration
Weight = mass X ___ gravity or acceleration due to gravity
acceleration = force divided by __ mass
a normal force is a ___ force support
the curved path a thrown or launched object on earth follows is called projectile motion
according to a = F/m, the greater the force applied to a mass, the greater it will ___ accelerate
N stands for___ newton
He dropped items from the Leaning Tower of Pisa to see if they would land at the same time. Galileo
In SI, velocity is measured in __ m/s
The SI unit of length is the ___ meter (m)
The SI unit of mass is the ___ kilogram (kg)
The greater the mass, the greater the ___ necessary to accelerate force
When forces are balanced, the net force equals ___ zero
Force equals mass times ___ acceleration
The net force of a falling object is weight minus ___. air resistance
When sitting on a chair, the chair is exerting a ____ force. normal
mass time gravity equals ___. weight
9.8 m/s squared is the acceleration due to gravity on ___. Earth
Earth has more gravity than the moon because of Earth's greater ___. mass
