Forces 1
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
F=ma
What is 4 N?
The sum of all forces acting on an object
What is Net force?
The force caused by gravity acting on a mass
What is Weight?
The speed of an object that travels 90 meters in 3 seconds
S = d/t
What is 30 m/s?
The mass of an object with a force of 180N if it moves with an acceleration of 8 m/s2
F=ma
What is 22.5 kg?
Newton's First Law of Motion is also called
What is the Law of Inertia?
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?
The net force in a tug of war when one team is pulling with a force of 120 N and the other 30 N
What is 90 N?
A force that opposes motion
What is Friction?
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?
A tablecloth can be pulled out from under a place setting because of
What is Inertia?
You multiply mass by this to get the weight
What is Gravity?
Your weight on the Earth if your mass is 37 kg
What is 362.6?
Two things the momentum of an object depends on
