Unit 5: MomentumWhat is momentum?- ✅✅ Momentum is the degree of an object's
opposition to a modification in motion. It is a vector quantity, indicating it
has both size and direction. The momentum formula is p = mv, where p is
momentum, m is mass, and v is velocity. This unit accounts for 12-18% of
the exam weight.
What is the formula for momentum?- ✅✅
The formula for momentum is p
= mv, where p is momentum, m is mass, and v is velocity.
What is impulse?- ✅✅ Impulse is the change in momentum of an object
over a given time period. It is the product of the force applied to an object
and the time over which the force is applied.
What is the unit of impulse?- ✅✅The unit of impulse is Ns
(newton-second).
What is the formula for impulse?- ✅✅ The formula for impulse is J = FΔt,
where J is impulse, F is the force applied, and Δt is the time interval over
which the force is applied.
What is conserved in a closed system?- ✅✅ Momentum is conserved in a
closed system, meaning the total momentum of the system before a
collision is equal to the total momentum after the collision.
What is the law of conservation of linear momentum?- ✅✅
According to
the law of conservation of linear momentum, the total momentum of a
system of objects remains constant if no external forces act on the system.
What are the three types of collisions?- ✅✅ The three types of collisions
are elastic collisions, inelastic collisions, and perfectly inelastic collisions.
