Physics 1: Force and its Measurements

Contact forces = Applied Force

Action at a distance force (Non-Contact forces) = Spring Force

Newton = It is the force acting on an object of mass 1 kg to give acceleration 1 m/s^2 Force = It is measured using the standard metric unit (SI unit)

<p>Force = Mass × Acceleration = Newton Newton = kg × m/s^2 = Standard metric unit for force measurement Force = Vector quantity with magnitude and direction Newton = The force acting on an object of mass 1 kg to give acceleration 1 m/s^2</p> Signup and view all the answers

<p>Gravitational force = Force of attraction between two masses Centripetal force = Force that keeps an object moving in a circular path Friction force = Force that opposes the motion of an object Tension force = Force transmitted through a string, rope, or wire when it is pulled tight</p> Signup and view all the answers

<p>Force can make a body at rest move = Force can change the direction of a moving body along with its shape and size Force can stop a moving body or slow it down = Force can accelerate the speed of a moving body Force can change the direction of a moving body along with its shape and size = Force can make a body at rest move Force can accelerate the speed of a moving body = Force can stop a moving body or slow it down</p> Signup and view all the answers

<p>External effect that affects the object and changes its state or direction = Concept of force An action which produces or tends to produce a change in a body’s state of rest or motion = Concept of force Interaction between an object and its environment resulting in a force upon each object = Introduction to force Forces existing as a result of interactions between objects = Introduction to force</p> Signup and view all the answers

<p>Forces only exist as a result of an interaction = When there is an interaction between two objects, there is a force upon each of the objects When the interaction vanishes, there is no force between the two objects = Forces describe the interactions between an object and its environment Forces describe the interactions between an object and its environment = When there is an interaction between two objects, there is a force upon each of the objects When there is an interaction between two objects, there is a force upon each of the objects = Forces only exist as a result of an interaction</p> Signup and view all the answers
