Physics with Earth Science 1st Semester Final

Front

What is the definition of net force?

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration and direction of motion.

Front

How do you calculate net force when two forces are acting in the same direction?

Back

Add the magnitudes of the two forces together.

Front

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

Back

Subtract the smaller force from the larger force and the direction will be that of the larger force.

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 does it mean for forces to be balanced?

Back

Balanced forces occur when the net force acting on an object is zero, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces occur when the net force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

Front

What is a line graph used for in physics?

Back

A line graph is used to show the relationship between two variables, typically showing how one variable changes in response to another.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the relationship between mass and force according to Newton's second law?

Back

According to Newton's second law, force (F) is equal to mass (m) times acceleration (a), expressed as F = m * a.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.
