Newtons Laws

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate or change its motion. It occurs when the total forces acting on an object are not equal.

Front

What is Newton's first law of motion?

Back

Newton's first law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an unbalanced 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 = m x a.

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 formula to calculate force?

Back

The formula to calculate force is F = m x a, where F is force, m is mass, and a is acceleration.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the SI system is the Newton (N).

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion. Unbalanced forces cause an object to accelerate or change its motion.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

What is weight?

Back

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