“center-seeking”

The center of motion

mass

All objects in circular motion move faster on the edge of the circle or in the middle?

The edge

Newton’s Second Law

Gravity

True

It depends on if there is air resistance or not.

1st: objects in motion, stay in motion, etc.

No, 2nd Law.

Daily Double First Law.

Explain Newton’s 2 First Law.nd Law in words.

Explain Newton’s 2nd Law in words. First Law.

A net force on a mass causes and acceleration.

The recoil of gun is explained by Newton’s 1 First Law.st Law. T or F.

F, Newton’s 3rd Law.

False, it is always accelerating.

Vx = v0 cosθ

Parabola
