Newton's Laws and Free Body Diagrams

Front

What is a free body diagram?

Back

A free body diagram is a visual representation of the forces acting on an object.

Front

What does Newton's first law of motion state?

Back

An object at rest will remain at rest and an object in motion will continue in motion with constant velocity, unless acted upon by a force.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is a force?

Back

A force is a push or pull acting upon an object.

Front

What is the formula for calculating net force?

Back

Net force is calculated by summing all the individual forces acting on an object, taking into account their direction.

Front

What is frictional force?

Back

Frictional force is the force that opposes the motion of an object in contact with a surface.

Front

How does mass affect gravitational force?

Back

The gravitational force between two objects increases with greater mass.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is the significance of the direction of forces in a free body diagram?

Back

The direction of forces in a free body diagram indicates the direction in which the forces are acting on the object.
