Forces & Newton's Laws REVIEW

Front

What is the net force on an object when two forces act in opposite directions?

Back

The net force is the difference between the two forces, acting in the direction of the larger force.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration.

Front

What does Newton's First Law of Motion state?

Back

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

Front

What is Newton's Second Law of Motion?

Back

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

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is gravity?

Back

Gravity is the force of attraction between two objects, such as the Earth and an object, pulling it downward.

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object that cancel each other out, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces occur when the total force acting on an object is not zero, causing the object to accelerate.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.

Front

What is the role of mass in Newton's Second Law?

Back

Mass is a measure of the amount of matter in an object and affects how much it will accelerate when a force is applied.
