A student is moving boxes. Box A and box B are the same size and shape . The student can lift box A, but not box B. What is the difference between the boxes?(1 point)
Responses
a Box B has more mass and takes less force to lift.
b Box B has more mass and takes more force to lift.
c Box A has more mass and takes less friction to lift.
d Box B has more mass and takes more friction to lift.
a Box B has more mass and takes less force to lift.
The correct answer is b) Box B has more mass and takes more force to lift.
To find the correct answer, we need to understand the relationship between mass and force when it comes to lifting objects.
The force required to lift an object depends on its mass. Mass is a measure of the amount of matter an object contains. In this case, we are told that Box A and Box B are the same size and shape, but the student can lift Box A and not Box B. This suggests that there is a difference in their masses.
The correct answer is b) Box B has more mass and takes more force to lift.
To determine why, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). In this case, since the boxes are not accelerating vertically (they are being lifted at a constant speed), we can rewrite the equation as F = m * g, where g is the acceleration due to gravity.
When comparing Box A and Box B, we find that Box B takes more force to lift. This implies that Box B has more mass. Since both boxes are the same size and shape, the additional mass in Box B makes it heavier and more difficult to lift. Therefore, the difference between the boxes is that Box B has more mass and takes more force to lift.
