Newton's Laws of Motion Concepts

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion. It is not equal in size and opposite in direction to other forces acting on the object.

Front

What happens when two forces of equal strength act in opposite directions?

Back

The object will not move at all because the forces are balanced.

Front

What do the letters F, m, and a represent in physics?

Back

F represents Force, m represents Mass, and a represents Acceleration.

Front

What does Newton's 1st Law of Motion state?

Back

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

Front

What is the difference between action and reaction forces?

Back

Action and reaction forces are equal in size but opposite in direction. They occur simultaneously and do not cancel each other out.

Front

What is a balanced force?

Back

A balanced force is when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that 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 gravitational force?

Back

Gravitational force is the attractive force between two objects due to their mass. It pulls objects toward each other.

Front

What is frictional force?

Back

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