11/14/24 Newtons First Law

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 stays in motion unless acted upon by an external force.

Front

What does Newton's First Law state?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will continue in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms or grams. It is directly related to the object's inertia.

Front

What factors affect gravitational pull between two objects?

Back

The gravitational pull between two objects is affected by their masses and the distance between them.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia. This means heavier objects are harder to start or stop moving than lighter ones.

Front

What is an example of an object at rest?

Back

A book lying on a table is an example of an object at rest.

Front

What is an example of an object in motion?

Back

A car driving down the road is an example of an object in motion.

Front

What is an external force?

Back

An external force is any force that comes from outside an object and can change its state of motion, such as friction, gravity, or a push.

Front

True or False: An object will stop moving if no external force acts on it.

Back

False. According to Newton's First Law, an object in motion will continue moving unless acted upon by an external force.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact with each other.
