Newton's Law 1/2

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is inertia?

Back

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

Front

What is friction?

Back

Friction is a force that resists the motion of two surfaces sliding against each other.

Front

What is gravity?

Back

Gravity is the force that pulls all objects toward the center of the Earth.

Front

What is a contact force?

Back

A contact force is a force that acts on an object through direct contact.

Front

What is the relationship between mass and inertia?

Back

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

Front

What happens to a ball rolling on the ground when friction is present?

Back

The ball will slow down and eventually stop due to the force of friction.

Front

What is the effect of gravity on falling objects?

Back

Gravity causes all objects to accelerate towards the Earth at approximately 9.8 m/s².

Front

How does Newton's 2nd Law of Motion relate to force and acceleration?

Back

Newton's 2nd Law states that force equals mass times acceleration (F=ma).

Front

What is an example of Newton's 1st Law in everyday life?

Back

When a car suddenly stops, passengers lurch forward due to inertia.
