Centripetal Force

​Actual definition:

An object will maintain its state of motion, whether at rest or in motion, unless an external force causes it to change.

Newton's 1st Law

the force applied to an object is equal to its mass multiplied by its acceleration, or

𝐹=𝑚𝑎

. This law explains that an object's acceleration is dependent on both its mass and the amount of force applied to it.

Mass

the force of gravity on an object

Weight

a pull or push that is applied to an object

Actual Definition

Make your own prediction about the definition in you notes.

Force

a situation where multiple forces acting on an object are equal in magnitude but opposite in direction, effectively canceling each other out, resulting in no net force and causing the object to remain stationary or move at a constant velocity

Actual Definition

Balanced Forces

a set of forces acting on an object where the net force is not zero, meaning the forces are not equal in magnitude or direction, causing the object to accelerate or change its state of motion
