Newton's Laws

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

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. It can be expressed with the formula 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.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that refers to the speed of an object in a specific direction.

Front

What is force?

Back

Force is a push or pull on an object that can cause it to accelerate, change direction, or change shape. It is measured in newtons (N).

Front

What is the formula for calculating acceleration?

Back

Acceleration can be calculated using the formula a = F/m, where 'a' is acceleration, 'F' is net force, and 'm' is mass.

Front

What is the unit of force?

Back

The unit of force is the newton (N), which is defined as the force required to accelerate a one-kilogram mass by one meter per second squared.

Front

What is balanced force?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in a net force of zero and no change in motion.

Front

What is unbalanced force?

Back

Unbalanced forces are forces that are not equal and opposite, resulting in a net force that causes an object to accelerate or change its motion.
