P2 Semester Flashcard

Front

What is Newton's Third Law of Motion?

Back

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

Front

How does mass affect the force needed to move an object?

Back

The greater the mass, the more force is needed to move it.

Front

What is the difference between speed and velocity?

Back

Velocity includes direction, while speed does not.

Front

What happens to the force needed to accelerate an object if its mass increases?

Back

More force is needed to achieve the same acceleration.

Front

What is thrust in the context of rocket launches?

Back

Thrust is the force that propels the rocket upward.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).

Front

What is inertia?

Back

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

Front

What is the relationship between force and acceleration?

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses.

Front

What is the role of friction in motion?

Back

Friction opposes the motion of an object and can affect the force needed to move it.
