What is Newton's First Law of Motion?

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

What is Newton's Second Law of Motion?

The acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.

What is Newton's Third Law of Motion?

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

What is inertia?

The tendency of an object to resist changes in its state of motion.

What is the formula for force?

Force = mass x acceleration

What is the SI unit of force?

Newton (N)

What is the net force acting on an object when it is in equilibrium?

The net force is zero.

Give an example of Newton's First Law of Motion.

A ball rolling on a flat surface will eventually stop due to friction.

Give an example of Newton's Second Law of Motion.

A heavier object requires more force to accelerate than a lighter object.

Give an example of Newton's Third Law of Motion.

When you push against a wall, the wall pushes back with an equal force.

What are the three laws of motion formulated by Sir Isaac Newton?

1. An object at rest will stay at rest, and an object in motion will stay in motion, with the same speed and in the same direction, unless acted upon by an unbalanced force. 2. The acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. 3. For every action, there is an equal and opposite reaction.

What is the relationship between force, mass, and acceleration according to Newton's Second Law of Motion?

Force is equal to mass multiplied by acceleration (F = ma).

What happens to the motion of an object when the net force acting on it is zero?

The object remains at rest or continues to move with a constant velocity.

What does Newton's Third Law of Motion state about the forces acting between two objects?

The forces are equal in magnitude and opposite in direction.

What are the two types of forces discussed in Newton's Laws of Motion?

Contact forces and non-contact forces.
