Forces and Newton's Laws

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 at a constant velocity unless acted upon by an unbalanced force.

Front

Define inertia.

Back

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

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object.

Front

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

Back

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

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, changing its motion.

Front

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

Back

If a 10 kg object is pushed with a force of 20 N, it will accelerate at 2 m/s² (F=ma).

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

Explain the concept of action and reaction forces.

Back

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

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.
