What is the definition of acceleration in science?

• The rate at which velocity changes

• The speed of an object

• The direction of an object's movement

• The mass of an object

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

• Acceleration is directly proportional to force and inversely proportional to mass

• Acceleration is directly proportional to mass and inversely proportional to force

• Acceleration is directly proportional to both force and mass

• Acceleration is inversely proportional to both force and mass

How can acceleration be calculated using a velocity versus time graph?

• By finding the slope of the graph

• By finding the area under the graph

• By measuring the height of the graph

• By measuring the width of the graph

What happens to the acceleration of a cart if the force applied to it doubles, according to Newton's second law?

• The acceleration doubles

• The acceleration halves

• The acceleration remains the same

• The acceleration becomes zero

What unit is commonly used to measure acceleration?

• Meters per second squared

• Miles per hour

• Kilograms

• Newtons
