PHYSICS MIDTERM

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Force (F) / Mass (m)

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 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.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

How do you calculate net force when two forces are acting in opposite directions?

Back

Net Force = Force 1 - Force 2 (subtract the smaller force from the larger force).

Front

What is momentum?

Back

Momentum (p) is the product of an object's mass and its velocity (p = m * v).

Front

How does mass affect acceleration when the same force is applied?

Back

Greater mass results in less acceleration when the same force is applied (a = F/m).

Front

What is the relationship between linear speed and distance from the center in circular motion?

Back

The further an object is from the center, the greater its linear speed.

Front

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

Back

The unit of force is the 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.
