What equation can be used to directly calculate an object's momentum, ρ? - ANSρ = mv
What are the SI units for momentum? - ANSKg 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 - ANSSomeone
running into a brick wall
The impulse experienced by a body is equivalent to the body's change in what? -
ANSmomentum
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. - ANSMomentum is transferred and conserved.
Kinetic Energy is conserved.
What does the law of conservation of momentum state? - ANSM₁V₁i - 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. - ANSElastic Collision
Two objects stick together and move with a common velocity after colliding. Identify the type of
collision. - ANSPerfectly Inelastic Collision
After colliding, objects are deformed and lose some kinetic energy. Identify the type of collision. -
ANSInelastic Collision
When an object is moving with uniform circular motion, the centripetal acceleration of the object
is in what direction? - ANSTowards the center
What term describes a change in the speed of an object in circular motion? - ANSTangential
Acceleration
What is the term for the net force directed toward the center of an object's circular path? -
ANSCentripetal Force
What forces can be considered centripetal forces? - ANSFriction, tension, gravity
