Newton's law review 2024

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is the definition of 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 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 happens to gravitational force as distance between two objects decreases?

Back

The gravitational force increases as the distance between two objects decreases.

Front

What is the definition of tension in physics?

Back

Tension is the force transmitted through a string, rope, or wire when it is pulled tight by forces acting from opposite ends.

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 (F=ma).

Front

What is the definition of applied force?

Back

Applied force is a force that is applied to an object by a person or another object.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

Front

What is the definition of gravitational force?

Back

Gravitational force is the attractive force between two masses, which depends on their masses and the distance between them.

Front

What is the concept of inertia?

Back

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