Forces and Motion Review

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. (F = ma)

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity (p = mv).

Front

How does air resistance affect falling objects?

Back

Air resistance opposes the motion of falling objects, reducing their acceleration and eventually leading to terminal velocity.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

How does mass affect inertia?

Back

Inertia is the resistance of an object to change its state of motion; more mass means more inertia.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = ma, where m is mass and a is acceleration.

Front

What happens to the momentum of an object when it collides with another object?

Back

Momentum is conserved in a closed system; the total momentum before the collision equals the total momentum after the collision.
