The soccer ball requires the strongest force to lift because it has the most mass.
The soccer ball requires the strongest force to lift because it has the most mass.
To determine which ball requires the strongest force to lift, we need to compare the weights of the balls. Weight is measured in grams.
Given the weights of the balls:
- Beach ball force = 110 g
- Soccer ball force = 410 g
- Baseball force = 143 g
- Golf ball force = 46 g
We want to find the ball with the highest weight, which will require the strongest force to lift.
Comparing the weights, we can see that the soccer ball has the highest weight of 410 g. Therefore, the soccer ball requires the strongest force to lift because it has the most mass.
So, the correct response is: The soccer ball requires the strongest force to lift because it has the most mass.

An object’s direction’s rate of change
An object’s direction’s rate of change
An object’s speed in a specific direction
An object’s velocity’s rate of change
are you sure??
I apologize for the confusion. You are correct. Acceleration is the rate of change of an object's velocity, not the rate of change of its direction. Thank you for pointing out the error. The correct response is:
An object’s velocity’s rate of change.
A motorcycle goes north at 40 miles per hour. A car goes south at 40 miles per hour on the same street. Which statement is true?(1 point)
Responses
The vehicles are going in opposite directions, so their speed is not the same.
The vehicles are going in opposite directions, so their speed is not the same.
The vehicles have the same speed, but different velocity.
The vehicles have the same speed, but different velocity.
The vehicles have the same velocity, but not the same speed.
The vehicles have the same velocity, but not the same speed.
The vehicles have the same speed and velocity.
The correct statement is:
The vehicles have the same speed, but different velocity.
Although both the motorcycle and the car are traveling at the same speed of 40 miles per hour, they are moving in opposite directions (north and south), resulting in different velocities.
