Physics Final Exam Review Day 1

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

How does mass affect motion?

Back

The greater the mass of an object, the greater the effect a force will have on its motion.

Front

When does an object have the greatest speed in a given time interval?

Back

An object has the greatest speed in the interval where it is accelerating the most, which can be determined from a speed-time graph.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity or force.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that is completely described by its magnitude alone, such as mass or temperature.

Front

Give an example of a vector quantity.

Back

An example of a vector quantity is velocity, which describes both speed and direction.

Front

Give an example of a scalar quantity.

Back

An example of a scalar quantity is temperature, which only has magnitude.

Front

What happens to an object's motion when unbalanced forces act on it?

Back

When unbalanced forces act on an object, it will accelerate in the direction of the net force.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F = ma).

Front

What is inertia?

Back

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