Honors Physics Fall Exam 2024

Front

What is the east component of a displacement vector when a car travels 20 miles at 30° north of east?

Back

17.3 miles

Front

Which is easier to push: a sports car or a minivan, and why?

Back

The sports car, because it has less mass and therefore less inertia.

Front

What happens when two objects are at the same place at the same time?

Back

They collided because they are in the same spot at the same time.

Front

What does Newton's F=ma Law state?

Back

It states that the force acting on an object is equal to the mass of that object multiplied by its acceleration.

Front

What is the resultant of two unit vectors at right angles to each other?

Back

2.83 N

Front

Define inertia.

Back

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

Front

What is the Law of Inertia?

Back

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

Front

How does mass affect acceleration according to Newton's second law?

Back

Increasing mass results in a decrease in acceleration if the force remains constant.

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction.

Front

What is a scalar?

Back

A scalar is a quantity that has only magnitude and no direction.
