Review on Newton's Laws of Motion and FBD

Front

What is Newton's 2nd Law of Motion?

Back

The force applied = the object's mass times the acceleration; F=ma.

Front

What does a Free Body Diagram (FBD) represent?

Back

A diagram showing all the forces acting on an object.

Front

What is centripetal acceleration?

Back

The change in velocity of an object traveling in a circular path.

Front

According to Newton's First Law of Motion, how long will an object remain at rest?

Back

Until an unbalanced force occurs.

Front

What is the definition of unbalanced forces?

Back

Forces that cause a change in the motion of an object.

Front

What does inertia refer to in physics?

Back

The tendency of an object to resist a change in its state of motion.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F=ma).

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the force is constant.

Front

What is the significance of the net force in a system?

Back

The total of all forces acting on an object; determines the object's motion.

Front

What happens to an object in motion according to Newton's First Law?

Back

It will remain in motion unless acted upon by an unbalanced force.
