Read About it: Acceleration

What is the definition of acceleration in science?

• The rate at which velocity changes

• The speed of an object

• The distance traveled over time

• The force applied to an object

According to Newton's second law, what happens to acceleration if the force on an object doubles while the mass remains constant?

• Acceleration doubles

• Acceleration halves

• Acceleration remains the same

• Acceleration becomes zero
