#181 (Q) Newton's Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

Force equals mass multiplied by acceleration (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

If the mass of an object is doubled, what happens to the acceleration if the force remains constant?

Back

The acceleration is halved.

Front

What does the equation F=ma represent?

Back

It represents Newton's 2nd Law of Motion, where F is force, m is mass, and a is acceleration.

Front

How does Newton's 1st Law apply to a passenger in a car that suddenly stops?

Back

The passenger continues to move forward due to inertia until restrained by a seatbelt.

Front

What is inertia?

Back

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

Front

Give an example of Newton's 3rd Law of Motion in action.

Back

When you jump off a small boat, you push the boat backward as you move forward.

Front

What happens to the acceleration of an object if the net force acting on it is zero?

Back

The object will not accelerate; it will either remain at rest or continue moving at a constant velocity.

Front

What is the relationship between force, mass, and acceleration?

Back

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