To identify situations when position, velocity, and /or acceleration change, realizing that change can be in direction or magnitude. If an object's position is described by a function of time, r⃗ (t) (measured from a nonaccelerating reference frame), then the object's velocity is described by the time derivative of the position, v⃗ (t)=dr⃗ (t)dt, and the object's acceleration is described by the time derivative of the velocity, a⃗ (t)=dv⃗ (t)dt=d2r⃗ (t)dt2. It is often convenient to discuss the average of the latter two quantities between times t1 and t2: v⃗ avg(t1,t2)=r⃗ (t2)−r⃗ (t1)t2−t1 and a⃗ avg(t1,t2)=v⃗ (t2)−v⃗ (t1)t2−t1.

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
