Forces

Rockets can be used to specifically illustrate action/reaction which is which Newton’s law? 

If the sum of all the forces acting on a moving object is zero, the object will

The sum of all forces acting upon an object is known as:

If the mass of an object is decreased, its inertia

The more inertia that an object has, the more mass that it has.

Force is a quantity that is measured using the standard metric unit known as

Name the two types of friction

Which situation describes an object that has no unbalanced force acting on it?

What is the unit for acceleration?

Force exerted by a surface as an object moves across it.

An object persists in uniform motion in a straight line unless disturbed by an unbalanced force

Which object has the greatest inertia?

What is the acceleration of an object with a 42 Newton force that has a mass of a 6 kg?

Force equals mass times acceleration. F=m*a

Force applied to an object by another object or person

Force created when a large object (like a planet) attracts another toward it.

Force is not a vector quantity.

1 Newton = 1 kg • m/s2

The result of unbalanced forces

Force transmitted through a string, wire, rope, and or cable when objects are at both ends

Which body is in equilibrium?

10 N East + 10 N West =

Movement of an object in a straight line

Exerted by a spring  when objects are connected to both ends

Diagram used to visualize the magnitude and direction of all forces acting upon an object. 

Distance traveled per unit time

The resistance an object to a change in its state of motion.

A force is described as _________ or _________ that acts on an object.

Calculate the force of a 21 kg football player running at a rate of 3 m/s²

<-- 40 N + 20 N --> =

In a weightless environment, would it require a force to set an object in motion?

 30 N South + 50 N North =

20 N -->  + 20 N --> =

Frictional force which acts on objects travelling through air.

When all the forces acting upon an object balance 

Forces only exist as a result of an interaction.

Support force that is in contact with another stable object

Force that opposes motion between two surfaces

Calculate the mass of an object moving with a 20N force and an acceleration of 5m/s²   

For every action, there is an equal and opposite reaction
