Question | Answer |
---|---|
Gravity | The force which attracts objects towards one another, especially the force that makes things fall to the ground |
first law | the law of inertia: objects at rest will remain at rest unless acted upon by a force or object, and an object moving at a constant speed will continue to move at that speed unless acted upon by a force or object. |
second law | the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. Acceleration is produced when a force acts on a mass. The greater the mass of the object being accelerated, |
third law | every action, there is an equal and opposite reaction. |
Acceleration | The rate at which the velocity of an object changes over time. |
Force | Any interaction which tends to change the motion of an object. Force is a push or pull upon an object resulting from the object's interaction with another object. |
Speed | How fast an object is moving; usually measured by how much distance is covered in a certain amount of time. |
Velocity | How fast an object is moving and in which direction. Speed describes only how fast an object is moving, whereas velocity gives both how fast and in what direction the object is moving. |
Elasticity | The tendency of solid materials to return to their original shape after being deformed. Solid objects will deform when forces are applied on them. If the material is elastic, the object will return to its initial shape and size when these |
Trajectory | The path described by a projectile flying or an object moving under the action of given forces. |
Terminal Velocity | The maximum velocity attainable, especially by a freely falling body, under given conditions. Also known as terminal speed. |
Sound Waves | The form that sound takes when it passes through air, water, etc. |
Newton's Laws of Motion | ewton's Laws of Motions were invented by the famous English mathematician, physicist and astronomer Sir Isaac Newton |
