Physics Semester Review

Front

What is Newton's 1st Law of Motion?

Back

An object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

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 is Newton's 3rd Law of Motion?

Back

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

Front

What is the formula to calculate force?

Back

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

Front

What is frictional force?

Back

The force that opposes the relative motion of two surfaces in contact.

Front

What is weight force?

Back

The force exerted by gravity on an object, calculated as weight (W) = mass (m) × gravitational acceleration (g).

Front

What is thrust?

Back

The force that propels an object forward, often used in the context of engines or rockets.

Front

What is buoyant force?

Back

The upward force exerted by a fluid on an object submerged in it, which opposes the weight of the object.

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases for a given force.
