Two vectors at the right angle that add up to a give vector are known as what? | Components |
Any object that moves through the air or space is what? | Projectile |
Two values that change in opposite directions is what? | Inversely |
The relationship among or objects mass,an object acceleration,and the net force on an objects called what? | Newton's second law |
Liquid and gasses are called what? | Fluids |
What does pressure means? | The amount of force per unit area. |
A diagram showing all the forces acting on an object is called? | Free-body |
What does vector quantity means? | A quantity in physics,such as force,that has both magnitude and directions. |
What does scalar quantity mean? | A physical measurement that does not contain directional information |
What does components mean? | A vector parallel to the x-axis and another parallel to the y-axis. |
What does vector resolution means? | The process of breaking a vector into its components |
What does projectile mean? | An object moving through space and affected only by gravity. |
What does trajectory mean? | The path of a projectile |
How does an increase in mass affect acceleration | If the force is constant , the acceleration is decreased |
Newton's second law of motion | Acceleration is directly proportional to the net force and inversely proportional to the mass of an object. |
Pressure | Force per unit area |
Pascal | A unit of pressure equal to one newton per square meter |
Fluids | A substance that can flow and therefore take the shape of its container ,a liquid or a gas |
Free-body diagram | A diagram showing all the forces acting on an object |
Terminal speed | The speed at which the acceleration of a failing object is zero because friction balances the weight |
Forces | A push or pull |
