What is the difference between mass and weight?

• Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

• Mass is the force exerted by gravity, while weight is the amount of matter in an object.

• Mass and weight are the same and can be used interchangeably.

• Weight is the measure of an object's volume, while mass is the measure of its density.

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

• Joule (J)

• Newton (N)

• Pascal (Pa)

• Watt (W)

How does mass affect the acceleration of an object when the same force is applied?

• A greater mass results in more acceleration when the same force is applied.

• A greater mass results in less acceleration when the same force is applied, as per the formula a = F/m.

• Mass has no effect on acceleration when the same force is applied.

• Acceleration is independent of mass when the same force is applied.

What does acceleration mean in physics?

• Acceleration is the rate of change of velocity of an object over time.

• Acceleration is the speed of an object in a given direction.

• Acceleration is the total distance traveled by an object.

• Acceleration is the force applied to an object divided by its mass.

What is the unit of acceleration?

• meters per second squared (m/s²)

• kilometers per hour (km/h)

• meters per second (m/s)

• feet per second squared (ft/s²)

What is the relationship between mass and acceleration when a constant force is applied?

• An increase in mass results in an increase in acceleration.

• An increase in mass results in a decrease in acceleration.

• Mass and acceleration are independent of each other.

• An increase in mass has no effect on acceleration.

If an object has a mass of 5 kg and is accelerating at 2 m/s², what is the force acting on it?

• 5 N

• 10 N

• 15 N

• 20 N

What is Newton's Second Law of Motion?

• Newton's Second Law states that an object at rest stays at rest unless acted upon by a force.

• Newton's Second Law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

• Newton's Second Law states that for every action, there is an equal and opposite reaction.

• 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.

What happens to the acceleration of an object if the force acting on it is doubled while its mass remains constant?

• The acceleration will double.

• The acceleration will remain the same.

• The acceleration will decrease by half.

• The acceleration will quadruple.

If a box has a mass of 10 kg and requires a force of 90 N to move, what is its acceleration?

• 5 m/s²

• 7 m/s²

• 9 m/s²

• 11 m/s²
