Force and Motion

What is the formula to calculate force?

• force = mass + acceleration

• force = mass - acceleration

• force = mass / acceleration

• force = mass x acceleration

What is the SI unit of force?

• Meter

• Second

• Newton

• Kilogram

What is the difference between mass and weight?

• Mass is a measure of the weight of an object, while weight is a measure of the volume of an object.

• Mass and weight are the same thing.

• Mass is a measure of the amount of matter in an object, while weight is the force exerted on an object due to gravity.

• Mass is a measure of the force exerted on an object due to gravity, while weight is a measure of the amount of matter in an object.

What is Newton's first law of motion?

• An object's velocity will increase indefinitely when acted upon by an unbalanced force

• An object at rest will remain at rest and an object in motion will remain in motion with a constant velocity unless acted upon by an unbalanced force.

• An object in motion will eventually come to a stop on its own

• An object at rest will eventually start moving on its own

What is the formula to calculate acceleration?

• a = (v_f + v_i) * t

• a = v_f + v_i / t

• a = (v_f - v_i) / t

• a = v_f * v_i / t

What is the relationship between force, mass, and acceleration?

• Force is directly proportional to mass but not acceleration.

• Force is directly proportional to mass and acceleration.

• Force is inversely proportional to mass and acceleration.

• Force is only related to mass and not acceleration.

What is the difference between speed and velocity?

• Speed is a scalar quantity, while velocity is a vector quantity.

• Velocity includes direction, while speed does not.

• Speed and velocity are the same thing.

• Velocity is the distance traveled per unit time, while speed is the rate of change of velocity.

What is Newton's second law of motion?

• The force acting on an object is equal to the velocity of the object multiplied by its mass.

• The force acting on an object is equal to the distance traveled by the object divided by the time taken.

• The force acting on an object is equal to the weight of the object divided by its mass.

• The force acting on an object is equal to the mass of the object multiplied by its acceleration.

What is the formula to calculate momentum?

• momentum = mass × velocity

• momentum = mass / velocity

• momentum = mass + velocity

• momentum = mass - velocity

What is Newton's third law of motion?

• Newton's third law of motion states that objects at rest tend to stay at rest.

• For every action, there is no reaction.

• Every action has an equal and opposite reaction.

• For every action, there is an equal and opposite reaction.
