Law of Acceleration

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 weight of the object multiplied by its acceleration.
• 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 velocity of the object multiplied by its mass.

State the formula for Newton's second law of motion.

• F = mv
• F = ma
• F = ma^2
• F = m/a

According to Newton's second law, what happens to the acceleration of an object when the net force acting on it increases?

• The acceleration of the object decreases.
• The acceleration of the object remains the same.
• The acceleration of the object becomes zero.
• The acceleration of the object increases.

According to Newton's second law, what happens to the acceleration of an object when the mass of the object increases?

• decreases
• becomes negative
• increases
• stays the same

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

• Acceleration causes force.
• Force has no effect on acceleration.
• Force and acceleration are directly proportional.
• Force and acceleration are inversely proportional.

If the force acting on an object is doubled, how does the acceleration change?

• The acceleration doubles.
• The acceleration quadruples.
• The acceleration is halved.
• The acceleration remains the same.

If the mass of an object is halved, how does the acceleration change?

• The acceleration remains the same.
• The acceleration doubles.
• The acceleration quadruples.
• The acceleration decreases by half.
