Test Review Force and Motion

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms. It is also a measure of an object's inertia.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object with greater mass has greater inertia.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is a balanced force?

Back

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

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

What is the relationship between force and acceleration?

Back

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

Front

What does a negative acceleration indicate?

Back

Negative acceleration, or deceleration, indicates that an object is slowing down.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is the significance of a graph showing motion?

Back

A motion graph visually represents an object's position, velocity, and acceleration over time, helping to analyze its movement.

Front

What does it mean for a chemical equation to be balanced?

Back

A balanced chemical equation has the same number of atoms of each element on both sides, ensuring the law of conservation of mass is followed.
