Forces Test

flashcards on different forces

What is a force? A push or a pull that acts on an object.
What are forces measured in? Newtons
What is friction? A force that opposes the motion of objects that touch as they move past each other
What are the four types of friction? Static Friction, Sliding friction, Rolling friction, and Fluid Friction
What is gravity? A force that acts between any two masses
What is projectile motion? The motion of a falling object after it is given an initial forward velocity
What is weight? The force of gravity acting on an object
What is mass? The amount of matter in an object.
What is Newton’s first law of motion? The state of motion of an object does not change as long as the net force acting on the object is zero
What is inertia? The tendency of an object to resist a change in it’s motion
What is Newton’s second law of motion? F=M(A)
What is Newton’s third law of motion? Whenever one object exerts a force on the second object, the second object exerts a equal and opposite force on the first object
Do action and reaction forces cancel? Action and Reaction forces do not cancel
What are net forces? The overall force acting on an object after all the forces are combined
