Calculating Force, Momentum, Speed, and Acceleration

What is the formula to calculate force?

• force = mass + acceleration

• force = mass / acceleration

• force = mass * acceleration

• force = mass - acceleration

A car with a mass of 1000 kg accelerates at a rate of 5 m/s^2. What is the force exerted on the car?

• 5000 N

• 10000 N

• 2500 N

• 100 N

What is the SI unit of force?

• Meter (m)

• Second (s)

• Kilogram (kg)

• Newton (N)

A 2 kg object is moving with a velocity of 3 m/s. What is its momentum?

• 6 kg*m/s

• 10 kg*m/s

• 8 kg*m/s

• 5 kg*m/s

What is the formula to calculate momentum?

• p = mv

• p = m^2v

• p = mv^2

• p = ma

A 0.5 kg ball is thrown with a velocity of 10 m/s. What is its momentum?

• 0.05 kg*m/s

• 50 kg*m/s

• 0.5 kg/s

• 5 kg*m/s

What is Newton's second law of motion?

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

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

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

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

A force of 20 N is applied to an object with a mass of 5 kg. What is the acceleration of the object?

• 8 m/s^2

• 6 m/s^2

• 2 m/s^2

• 4 m/s^2

What is the relationship between force, mass, and acceleration according to Newton's second law?

• Force is inversely proportional to mass and acceleration.

• Force is directly proportional to mass but not acceleration.

• Force is directly proportional to acceleration but not mass.

• Force is directly proportional to mass and acceleration.

A 1000 kg car accelerates at a rate of 2 m/s^2. What is the force exerted on the car?

• 1000 N

• 500 N

• 4000 N

• 2000 N
