Pre AP Forces and Newton's Laws

Front

What is the unit of force measured in?

Back

Newton

Front

What is the net force on the couch if your dad pushes with a force of 35 N to the right and you push with a force of 25 N to the right?

Back

60 N right

Front

What is the missing force when discussing forces acting on an object?

Back

normal force

Front

The more mass an object has, the more __________ it has; and the more it wants to stay as is (rest or motion).

Back

inertia

Front

Define friction.

Back

Friction is the force that opposes motion between two surfaces that are touching.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What does Newton's Second Law of Motion state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is the definition of weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W=mg).

Front

What is the role of the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with a surface, acting perpendicular to the surface.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
