Unit 2 Exam Review Physical Science

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = mass (m) × velocity (v).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it is directly related to the object's mass.

Front

What is the relationship between mass and force in stopping an object?

Back

The greater the mass of an object, the more force is required to stop it, assuming the same speed.

Front

What is position in physics?

Back

Position is a variable that indicates the location of an object relative to a reference point or origin.

Front

What does Newton's 1st Law of Motion state?

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 does Newton's 2nd Law of Motion state?

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 does Newton's 3rd Law of Motion state?

Back

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

Front

What is a positive direction on a graph?

Back

Positive directions on a graph typically include North, East, and Up.

Front

What is a negative direction on a graph?

Back

Negative directions on a graph typically include South, West, and Down.
