Front

What is a Free Body Diagram (FBD)?

Back

A graphical representation used to visualize the forces acting on an object.

Front

What does Newton's First Law state?

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 is the definition of frictional force?

Back

The force that opposes the relative motion of two surfaces in contact.

Front

How does the angle of an incline affect the normal force?

Back

As the angle of the incline increases, the normal force decreases.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object, calculated as weight = mass × gravity.

Front

What is the principle of action and reaction?

Back

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

Front

What is the formula for calculating frictional force?

Back

Frictional force = coefficient of friction × normal force.

Front

What happens to the acceleration of an object if the net force acting on it is zero?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is the significance of the coefficient of friction?

Back

It quantifies the amount of frictional force between two surfaces.

Front

How do you determine the net force acting on an object?

Back

Net force is the vector sum of all forces acting on the object.
