Fundamentals of Physics - Unit 1

What is the SI unit of force?

• Joule (J)

• Watt (W)

• Pascal (Pa)

• Newton (N)

Which of the following is a vector quantity?

• Temperature

• Velocity

• Mass

• Speed

What is the formula for calculating work done?

• Work = Force + Distance

• Work = Force × Distance × cos(θ)

• Work = Force - Distance

• Work = Force / Distance

In which type of collision is kinetic energy conserved?

• Perfectly inelastic collision

• Superelastic collision

• Inelastic collision

• Elastic collision

What does Newton's first law of motion state?

• An object will change direction only if a force is applied.

• An object will accelerate if no force is applied.

• An object will remain at rest or in uniform motion unless acted upon by an external force.

• An object will remain in motion only if it is in a vacuum.
