INT 1st Law & FBD Flashcard

Front

What is the force of attraction (pulling) between two objects that every object experiences on Earth?

Back

Gravitational force.

Front

What does the law of inertia state about an object's motion?

Back

An object will continue moving at the same velocity unless an outside force acts on it, and an object at rest will stay at rest unless acted on by an outside force.

Front

True or False: Inertia is a property that only some material objects possess.

Back

False. Inertia is a property that all objects with mass possess.

Front

What type of force occurs when one object pushes or pulls on another object by touching it?

Back

Applied force.

Front

What happens when an automobile you are riding in suddenly stops, but you continue to go forward?

Back

This demonstrates Newton's 1st Law of Motion.

Front

Define inertia in the context of physics.

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 the formula for calculating gravitational force between two objects?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.

Front

What is the difference between contact forces and non-contact forces?

Back

Contact forces require physical contact between objects, while non-contact forces act at a distance (e.g., gravitational force).

Front

What is an example of a non-contact force?

Back

Gravitational force.
