BCA: 6th Grade: Science: Balance and Unbalanced Forces

Front

Who formulated the three basic laws of motion in the 1600s?

Back

Sir Isaac Newton

Front

What is the term for when the speed of an object remains the same, without increasing or decreasing?

Back

Constant speed

Front

Forces may or may not cause what?

Back

Movement

Front

What is the force that causes a moving object to slow down when it touches another object?

Back

Friction

Front

What is Newton's First Law of Motion, also known as the Law of Inertia?

Back

An object at rest tends to stay at rest unless acted on by an unbalanced force, and an object in motion tends to stay in motion with the same speed and direction until acted on by an unbalanced force.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not cause a change in motion, while unbalanced forces result in a change in motion.

Front

What is the net force acting on an object?

Back

The vector sum of all the forces acting on the 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 speed.

Front

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

Back

Newton (N)

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, causing it to slow down or stop.
