Q2 21st Century Science Final 24-25

Front

What is Force?

Back

Force is defined as mass multiplied by acceleration (F = m * a).

Front

What does Newton's 3rd Law state?

Back

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

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in magnitude and act in opposite directions, resulting in no change in motion.

Front

What happens when the force on an object is doubled?

Back

According to Newton's 2nd Law, if the force on an object is doubled, the acceleration is also doubled.

Front

What occurs when forces are balanced?

Back

When forces are balanced, an object will not move.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is Newton's 1st Law?

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) can be calculated using the formula a = F/m, where F is force and m is mass.

Front

What is the relationship between mass and acceleration?

Back

Mass and acceleration are inversely related; as mass increases, acceleration decreases if the force remains constant.
