What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the more inertia it possesses.

What is Newton's First Law of Motion?

Back

Newton's First 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 Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed as F=ma.

Front

What is Newton's Third Law of Motion?

Back

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

What is friction?

Back

Friction is a force that opposes the motion of an object. It acts in the opposite direction to the applied force.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state. For example, gravitational potential energy depends on an object's height.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that do not cancel each other out, resulting in a change in the motion of an object.

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.
