PS2 1 Newton's Second Law

HS-PS2-1 Motion and Stability: Forces and Interactions

Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.

Newton's First Law

An object either remains at rest or continues to move at a constant velocity, unless acted upon by a force

Sum of forces = 0 Change in velocity dv/dt = 0

An object that is at rest will stay at rest unless a force acts upon it.

An object that is in motion will not change its velocity unless a force acts upon it.

The property where massive bodies resist changes in motion is called inertia

Composites

Cement pastes mixed in space (above) and on the ground (below). The sample from space shows more porosity, or open spaces in the material, which affects concrete strength. Crystals in the Earth sample also are more segregated. NASA Penn State MCL
