Bill Nye Motion

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion continues in motion unless acted upon by an outside force.

Front

Do asteroids in space have inertia?

Back

Yes, asteroids in space have inertia despite not having weight.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law of Motion states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an external force.

Front

Can objects that are not moving have inertia?

Back

True, objects that are not moving also have inertia; they resist changes to their state of rest.

Front

What happens to a moving object if no external force acts on it?

Back

If no external force acts on a moving object, it will continue to move at a constant velocity.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia. Heavier objects are harder to accelerate or decelerate.

Front

How does inertia affect everyday objects?

Back

Inertia affects everyday objects by causing them to resist changes in their motion, such as when a car suddenly stops and passengers lurch forward.

Front

What is an example of inertia in action?

Back

An example of inertia is a soccer ball that remains at rest until kicked, or a rolling ball that continues to roll until friction or another force stops it.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object and does not change regardless of location, while weight is the force of gravity acting on that mass and can change depending on the gravitational field.

Front

What role does friction play in motion?

Back

Friction is a force that opposes motion between two surfaces in contact, causing objects to slow down or stop.
