Review: 1st Semester Physics

Front

What is the vertical acceleration of a projectile?

Back

-9.81 m/s²

Front

Forces always act in equal and opposite pairs. Which law does this statement represent?

Back

Newton's 3rd Law

Front

Determine the acceleration that results when a 12-N net force is applied to a 3-kg object.

Back

4 m/s²

Front

What is the missing force in the context of motion?

Back

F_f (frictional force)

Front

Energy of motion is which type of energy?

Back

Kinetic Energy

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 unless acted upon by a net external force.

Front

What is the formula for calculating force?

Back

F = m * a (Force = mass × acceleration)

Front

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

Back

Newton (N)

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

What is the acceleration due to gravity on Earth?

Back

-9.81 m/s²
