Opposes the motion - Study guides, Study notes & Summaries

Honors Physics Final Exam Questions and Answers Graded A+ What is the principle of inertia? The principle of inertia states that an object will not change its state of motion unless acted upon by an external force. How does friction affect the motion of an object? Friction opposes the motion of an object, causing it to slow down or stop. What is the concept of momentum? Momentum is the quantity of motion an object has, which depends on its mass and velocity. What is the dif...

Newton's First Law (Law of Inertia) correct answers An object in motion (or at rest) will tend to stay in motion (or at rest) until it is acted upon by an outside force. Interia correct answers The tendency of an object to resist a change in velocity whether the object is in motion or motionless kinetic friction correct answers when the surface of one object slides along the surface of another object, static friction overcome. size of the friction force increases with an object's weight....

rate at which work is done; depends on the time it takes power What is the unit for power? Watts, Horsepower (1 hp=746 Watts) done when a force causes an object to be displaced or moved (examples: push/moved) work What is the unit for work? Nm, J When is work done? object must be displaced (moved) for work to take place Work is only done when the force is __________ to the displacement. If the force on an object is not parallel to the object's motion, the...
