Force

The video tutorial introduces the concept of forces, focusing on unbalanced forces and their effects on objects, such as causing acceleration or deceleration. It explains how force is measured in Newtons, named after Sir Isaac Newton, who defined the concept in his laws of motion.

What happens when an unbalanced force is applied to an object?

• The object remains stationary.

• The object changes its shape.

• The object starts to move or changes its motion.

• The object becomes lighter.

How can forces affect the motion of an object?

• They can only make an object move faster.

• They can cause an object to accelerate or decelerate.

• They can only stop an object from moving.

• They have no effect on the motion of an object.

In what unit is force measured?

• Watts

• Newtons

• Pascals

• Joules

Who is credited with defining the concept of force in his laws of motion?

• Nikola Tesla

• Sir Isaac Newton

• Galileo Galilei

• Albert Einstein

What is the significance of Newtons in the context of force?

• It is a unit of force.

• It is a unit of pressure.

• It is a unit of power.

• It is a unit of energy.
