Force 1
The force an object must overcome to begin moving is this.
What is static friction?
This is the unit for weight.
What are Newton?
The roughness of surfaces is described using this term.
What is coefficient of friction (µ)?
This value increases with mass.
What is inertia?
The force of friction that occurs when one object slides over another is known as this.
What is sliding friction?
This is the unit for mass commonly used in Physics.
What is the kilogram?
Inertia is a property of this Law of Physics.
What is Newton’s First Law?
This the force that resists motion.
What is friction?
Newton’s Second Law uses this formula.
What is F = ma?
This is the force pulling an object down.
What is weight?
Equal and opposite forces being exerted by two interacting objects is part of this Law of Physics.
What is Newton’s Third Law?
An object’s resistance to change is known as this.
What is inertia?
Force uses this unit.
What is the Newton?
This is why a train is harder to stop than a car even if both are going the same velocity.
What is the train has more mass or inertia?
Newton’s Third Law states this.
What is whenever one object exerts a force on a second object, the second object also exerts a force on the first object, equal in magnitude and opposite in direction?
Requiring more force to move more massive objects is part of this Law of Physics.
What is Newton’s Second Law?
This is the quantity used to describe the acceleration due to gravity, g?
What is 9.81 m/s2?
The amount of matter in an object is known as this.
What is mass?
Newton’s First Law states this.
What is an object at rest will stay at rest and an object in motion will remain in motion?
The equal and opposite force that a surface exerts on an object is known as this.
What is the normal force?
This is what causes friction.
What are interacting micro-surfaces?
If a mass has a weight of 50N and is sitting motionless on the ground, this is the quantity of the normal force exerted on the mass by the surface.
What is 50N?
This is a push or a pull?
What is force?
This is the unit for the coefficient of friction?
What is there is no unit?
Newton’s Second Law states this.
What is the acceleration of an object is directly proportional to the net force on the object and inversely proportional to the mass of the object?
