Balanced and Unbalanced Forces/Newton's Laws

Front

What is the sum of all forces acting on an object?

Back

Net Force

Front

What type of forces are acting when they do not cancel each other out?

Back

Unbalanced Forces

Front

What law states that an object at rest stays at rest and an object in motion stays in motion unless acted upon by a net external force?

Back

Newton's 1st Law of Motion

Front

What is the unit of measure for force that equals the force required to accelerate 1 kilogram of mass at 1 meter per second squared?

Back

Newton

Front

What force opposes the motion of an object when it slides over a surface?

Back

Friction

Front

What is the term for forces that are equal in size and opposite in direction, resulting in no change in motion?

Back

Balanced Forces

Front

What is the relationship between mass, acceleration, and net force according to Newton's 2nd Law?

Back

F = m * a (Force equals mass times acceleration)

Front

What is the action-reaction principle described in Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

How does friction affect the motion of an object going down a hill?

Back

Friction opposes the motion, making it harder to move down the hill.

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.
