Forces and Newton's Laws

Front

A lamp sitting on a table is demonstrating Newton's ___ Law.

Back

1st Law: An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

According to Newton’s second law of motion, force is equal to mass times ______________________.

Back

Acceleration: F = m * a, where F is force, m is mass, and a is acceleration.

Front

Sitting at the top of a steep hill on a roller coaster (not moving), is an example of:

Back

Inertia: The tendency of an object to resist changes in its state of motion.

Front

Which statement about gravity is true?

Back

Gravity causes objects to pull towards one another.

Front

In any collision (crash) the ______ is ALWAYS constant.

Back

Total Momentum: The total momentum before a collision equals the total momentum after the collision.

Front

What is Newton's 2nd Law of Motion?

Back

It states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

Define inertia.

Back

Inertia is the property of an object to remain at rest or in uniform motion unless acted upon by an external force.

Front

What is the formula for calculating force?

Back

F = m * a, where F is force, m is mass, and a is acceleration.

Front

What does gravity do to objects?

Back

Gravity pulls objects towards one another, giving them weight.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity (p = m * v).
