8.7 B Check #1

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law of Motion states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

Front

What does inertia mean?

Back

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

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What is an example of Newton's First Law of Motion?

Back

A book remaining at rest on a table until someone moves it.

Front

What happens to an object at rest when no external force acts on it?

Back

An object at rest will remain at rest until acted upon by an external force.

Front

How does gravity affect a roller coaster?

Back

Gravity causes the roller coaster to accelerate downwards, influencing its speed and direction.

Front

What is the net force acting on a 10 kg object at rest?

Back

The net force acting on a 10 kg object at rest is 0 N.

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

In Newton's Second Law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is an example of an action-reaction pair according to Newton's Third Law?

Back

When a rocket launches, the action is the rocket pushing down on the ground, and the reaction is the ground pushing the rocket upward.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if it changes its position relative to a reference point over time.
