In order to ride a bike up a hill with increasing speed—

the rider’s pedal force must be less than friction and the force of gravity
the rider’s pedal force must be equal to than friction and the force of gravity
the rider’s pedal force must be greater than friction and the force of gravity
It is impossible to ride up a hill with increasing speed.

Answers

Answer: the rider’s pedal force must be greater than friction and the force of gravity

Explanation:

This is because if the pedal force was less, you would go slower, and it is obviously not impossible to ride up a hill without increasing speed. But if the force was greater, your speed would increase.

What is the effect of the mass of an object on it’s friction threshold?

Answers

An object of large mass is pulled down onto a surface with a greater force than an object of low mass and, as a consequence, there is greater friction between the surface of the heavy object than between the surface and the light object.

According to Newton’s second law of motion, the relationship between an object's mass (m), its acceleration (a), and the applied force (F) is F = ma. How does this law apply to the sport of bowling?

When the pins are correctly aligned, their mass and acceleration will keep the ball from going into the gutter.

When the bowling ball is rolling down the lane, the mass of the ball on the floor makes the pins become unstable, allowing the acceleration of the ball to knock down the pins.

When the bowling ball is rolled with a force, this accelerates the ball. That acceleration, when combined with the mass of the ball, produces a force that knocks down the pins

When the bowling ball hits the pins, the ball has a mass, so it will exert acceleration on the pins and knock them down.

Answers

Answer:

When the bowling ball is rolled with a force, this accelerates the ball. That acceleration, when combined with the mass of the ball, produces a force that knocks down the pins.

Explanation:

That is because you accelerate the ball with a force when you roll it, and the mass of the ball has a force that knocks down the pins.

Answer:

When the bowling ball is rolled with a force, this accelerates the ball. That acceleration, when combined with the mass of the ball, produces a force that knocks down the pins. when the bowling ball id rolling with a force, this accelerates the ball. this is why the ball is combinding with the force of the mass of the ball.

A heavy box is dropped from the roof of a small building and is traveling to the ground. Which claim about the forces acting on the box must be true?
Choose 1 answer:
A. There are no forces on the box.
B. There is no net force on the box.
C. There is a net force on the box.
D. There is not enough information.

Answers

Answer:

C. There is a net force on the box.

Explanation:

If the box was stationary, sitting on the roof, the correct answer choice would be A. In this scenario, the box is fallign downward, meaning that there is a net force pushing the box downward.

Answer:

C: there is a net force on the box
