*****8th TEST: Newton's Laws of Motion

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 inertia?

Back

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

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 mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its state of motion.

Front

What happens to the total momentum in a closed system during a collision?

Back

The total momentum before the collision is equal to the total momentum after the collision.

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 is the relationship between force and acceleration?

Back

Force is directly proportional to acceleration; if the force increases, acceleration increases, assuming mass remains constant.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction of the applied force.
