Newton's Three Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

Define inertia.

Back

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

Front

What does it mean for a net force to be zero?

Back

When the net force acting on an object is zero, it means that all the forces acting on the object are balanced, resulting in no change in motion.

Front

Who formulated the laws of motion?

Back

Sir Isaac Newton.

What is required to change the motion of an object?

Back

An unbalanced force is required to change the motion of an object.

Explain 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 the formula for Newton's Second Law of Motion?

Back

F = ma, where F is the net force, m is the mass, and a is the acceleration.

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is Newton's Third Law of Motion?

Back

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

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

Back

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