The man responsible for the Laws of Motion
Who is Isaac Newton?
the rate of change of velocity
What is Acceleration?
The m in the equation F=ma represents
What is Mass?
The amount of force acted on a golf ball (0.2 kg) if it accelerates at a rate of 20 m/s2
What is 4 N?
The sum of all forces acting on an object
What is Net force?
This force is exerted when two objects are sliding past each other
Friction
The speed of an object that travels 90 meters in 3 seconds
What is 30 m/s?
The mass of an object with a force of 52N if it moves with an acceleration of 4 m/s2
What is 13 kg?
The force that keeps Earth in orbit
What is gravity
The net force acting on an object with constant velocity
What is 0 N?
The type of frictional force that acts on objects as they travel through the air
What is Air Resistance?
The equation of Newton's Second Law of Motion
What is F= ma?
The unit of measure for force
What is Newton?
The d in the speed equation s=d/t represents
What is Distance?
The acceleration of a 100 g box if you apply a net force of 3N
What is 30 m/s2?
Forces acting on an object that causes the object to move
What are Unbalanced Forces?
On a distance-time graph, the slope will give you this
What is speed
Deacceleration is show by this symbol
What is a minus sign
For every action, there is an equal and opposite reaction
WHat is Newton's Third Law of Motion?
Forces acting on an object that does not cause the object to move
What are Balanced Forces?
The number for acceleration due to gravity
What is 9.8 m/s2?
This force is described by F = MA
What is Newton's 2nd Law
You multiply mass by this to find gravity
What is gravitational acceleration
The unit for work
What is Joule
Two things a moving object depends on
What is Mass and Speed?
