1) What is Acceleration? a) The rate at which an object's velocity changes over time b) Speed in a specific direction; a vector quantity 2) What is a Contact Force? a) A contact force that opposes the relative motion of two surfaces in contact b) A force that arises from direct physical interaction between two objects 3) What is Energy? a) The ability to do work or cause change b) The energy that travels when something pushes it. 4) What is force? a) A force is a push or pull that can change an object's motion, speed, or direction. It can be caused by direct contact, like friction, or by action at a distance, like gravity. Forces are measured in newtons. b) Its literal meaning is an unreal or fictitious force. It means, a force which is not actually applied due to any real source, but yet your body feels it. 5) What is gravity? a) A gravity that helps people stays on the ground with a help from the force. b) A non-contact force of attraction between two masses 6) What is inertia? a) The rate at which work is done or energy is transferred b) The tendency of an object to resist changes in its state of motion (including rest) 7) What is Kinetic Energy? a) The energy of an object due to its motion b) The transfer of energy that occurs when a force is applied to an object, causing it to move 8) What is Mass? a) The rate at which an object's velocity changes over time b) The amount of matter in an object, typically measured in kilograms or grams 9) What is a Non-Contact Force? a) A force that slows things down when they rub against each other b) A force that acts on an object at a distance 10) What is a Potential Energy? a) The amount of matter in an object, typically measured in kilograms or grams b) Energy stored in an object due to its position or configuration 11) What is power? a) The rate at which work is done or energy is transferred b) The force that pulls things towards the Earth 12) What is Speed? a) How quickly something speeds up, slows down, or turns b) The rate at which an object moves, regardless of direction 13) What is Velocity? a) Speed in a specific direction; a vector quantity b) The rate at which work is done or energy is transferred 14) What s work? a) The transfer of energy that occurs when a force is applied to an object, causing it to move b) The rate at which an object moves, regardless of direction
