Newton's Law and Forces

Front

What is Inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the more inertia it has.

Front

Which has more Inertia: an 18 Wheeler, an Ant, a Car, or a Skateboard?

Back

An 18 Wheeler has more inertia because it has more mass.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion. It is not equal in size and opposite in direction to other forces acting on the object.

Front

What is the formula for Force?

Back

F = MA (Force equals mass times acceleration).

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 an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = MA).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What happens to an object's motion when a balanced force acts on it?

Back

The object's motion does not change; it remains at rest or continues to move at a constant velocity.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can occur when an object speeds up, slows down, or changes direction.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass. It pulls objects toward each other.
