Newton’s first law says that an object remains in uniform motion unless acted on by a net force. When a net force is applied, the object accelerates. Newton’s second law details the relationship between net force, the mass, and the acceleration: The acceleration of an object is in the direction of the net force.

Saying no will not stop you from seeing Etsy ads, but it may make them less relevant or more repetitive.string, and the accelerations of the blocks have the same magnitude. Note that we take the positive direction in the direction of the acceleration for each block. We write ·F = ma from the force diagram for each block: y-component (block 1): F T – m 1 g = m a; y-component (block 2): m 2 g – F T = m 2 a.
