A heavy brick weighs more than a fluffy cushion, but the cushion takes up more space. Which object has more matter? How do you know?

Answers

Answer 1

Answer:

The heavy brick has more matter. The amount of matter in an object is determined by its mass, which is a measure of the total amount of material in the object.

Which object has more matter?

In this situation, the brick is heavier, which means it is bigger and has more stuff inside compared to the soft cushion.

Weight is the push or pull on something because of gravity, and it can change depending on how strong the gravitational field is. But, mass is a basic characteristic of stuff that stays the same no matter the pull of gravity. The brick is heavier, so it has more stuff inside than the cushion.

A change in pressure applied to an enclosed fluid is transmitted undiminished to every point of the fluid and to the walls of the container. This is a statement of Pascal's Principle, which is the basis of the hydraulic jack you see lift cars at the garage.

A 430 g football is lying on the ground, then is kicked and is moving at 25 m/s. If the duration of the impact was 0.0010 s, what was the average force on the ball?

Answers

Tools used for this solution:
Impulse = change in momentum
Impulse = (force ) x (time applied)
Momentum = (mass) x (speed)
=================================
Momentum of the ball after the kick = (mass)x(speed) = 0.43kg x 25 m/s = 10.75 kg-m/s .

Impulse exerted by the kicker's toe = 10.75 kg-m/s .

(force) x (time) = 10.75 kg-m/s .

Force x 0.001 sec = 10.75 kg-m/s .

Divide each side by 0.001 sec :

Force = (10.75 kg-m/sec) / (0.001 sec) = 10,750 kg-m/s² = 10,750 newtons.

That's about 2,416 pounds from the kicker's toe, during that ¹/₁₀₀₀ of a second.
