mass and acceleration

• What does Newton's second law state about unbalanced forces on an object?

  If the forces on an object are unbalanced, then the object will accelerate.
• What are the three ways an object can accelerate according to Newton's second law?

  An object can speed up, slow down, or change direction.
• What two factors determine the acceleration of an object with an unbalanced force acting on it?

  The size of the force acting on it and the mass of the object.
• How does the size of the resultant force affect acceleration?

  A bigger resultant force causes a bigger acceleration, while a smaller resultant force causes a smaller acceleration.
• How does mass affect the acceleration of an object for a given force?

  A more massive object will accelerate less for a given force, while a less massive object will accelerate more for the same force.
• What is the equation that expresses Newton's second law?

  F = ma
• In the equation F = ma, what does F represent?

  F represents the resultant force in Newtons (N).
• In the equation F = ma, what does m represent?

  m represents the mass in kilograms (kg).
• In the equation F = ma, what does a represent?

  a represents the acceleration in meters per second squared (m/s²).
• Why are heavy objects harder to accelerate than light objects?

  Heavy objects are harder to get to speed up because they have more mass.
• What happens when you push harder on an object?

  The object speeds up faster.
