Honor Physics Final (Semester 1) Review

Front

The initial horizontal velocity of a projectile is ____ its final horizontal velocity.

Back

equal to

Front

Which of Newton's Laws states that an object in motion stays in motion unless acted upon by an external force?

Back

Newton's 1st Law of Motion

Front

What are physical quantities that have only magnitude and no direction called?

Back

Scalar quantities

Front

The horizontal component of a projectile's velocity is independent of which of the following?

Back

the vertical component

Front

What is the total displacement if Jerry walked from home to school and then from school to the park, resulting in a net distance of 2 km?

Back

2 km

Front

What is the formula for calculating the range of a projectile?

Back

Range = (initial velocity^2 * sin(2*angle)) / g

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What does the term 'inertia' refer to in physics?

Back

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

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.
