When physicists work on research, they rarely

write down force diagrams or use Newton’s Laws explicitly

but much easier, way to

calculate the motion of particles that

are under the influence of forces

You will learn about this in your engineering mechanics course

Last week someone asked me about the relationship

between KE and momentum (they look related)

This is a very deep observation
