What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. The greater the mass of an object, the greater its inertia.

Front

How does mass affect inertia?

Back

The inertia of an object is directly proportional to its mass. A 4kg mass has 4 times the inertia of a 1kg mass.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that 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

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that 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 Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

What is the normal force?

Back

The normal force is the force exerted by a surface that supports the weight of an object resting on it, acting perpendicular to the surface.

Front

What is friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies toward each other, acting downward toward the center of the Earth.

Front

What happens to the acceleration of a freely falling object?

Back

As a body falls freely near the surface of the Earth, its acceleration remains the same at approximately 9.81 m/s².

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as the product of mass and gravitational acceleration (W=mg).
