Ap Physics 1 - Final Exam Study GuideQuestions & Detailed Answers 2024
What equation can be used to directly calculate an object's momentum, ρ? -
ANS ρ = mv
What are the SI units for momentum? - ANS Kg x m/s
What equation can be used to directly calculate the change in an object's
momentum? - ANS ∆P = mvf - mvi
ΔP = FΔt
Example of something going through a significant change in Momentum -
ANS Someone running into a brick wall
The impulse experienced by a body is equivalent to the body's change in
what? - ANS momentum
Two objects with different masses collide and bounce back after an elastic
collision. Before the collision, the two objects were moving at velocities
equal in magnitude but opposite in direction. Describe what happens after
the collision. - ANS Momentum is transferred and conserved. Kinetic Energy
is conserved.
What does the law of conservation of momentum state? - ANS M₁V₁i - M₂V₂i
= M₁V₁f + M₂V₂f
Two objects move separately after colliding, and both the total of
momentum and total kinetic energy remain constant. Identify the type of
collision. - ANS Elastic Collision
,
Two objects stick together and move with a common velocity after colliding.
Identify the type of collision. - ANS Perfectly Inelastic Collision
After colliding, objects are deformed and lose some kinetic energy. Identify
the type of collision. - ANS Inelastic Collision
When an object is moving with uniform circular motion, the centripetal
acceleration of the object is in what direction? - ANS Towards the center
What term describes a change in the speed of an object in circular motion? -
ANS Tangential Acceleration
What is the term for the net force directed toward the center of an object's
circular path? - ANS Centripetal Force
What forces can be considered centripetal forces? - ANS Friction, tension,
gravity
When a car makes a sharp left turn, what causes the passengers to move
toward the right side of the car? - ANS Inertia
Tides are caused by... - ANS The change in Fg caused by the moon
Why does an astronaut weigh less on the moon than on Earth? - ANS The
moon has less mass and therefore less gravity
The degree to which an object attracts other object is measured by the
object's what? - ANS Mass
When calculating the gravitational force between two extended bodies, you
should measure the distance from which point? - ANS Center of mass
