How does car brakes change physical forces related to:

•Collision

•Velocity during impact

•Acceleration/Deceleration

• Force of impact

•Momentum

A lump of putty and a rubber ball have equal mass. both are thrown with equal speed against a wall. the putty sticks to the wall. the ball bounces back at nearly the same speed with which it hit the wall.

Calculate the force on an object that has a mass of 12 kg and an acceleration of 4 m/s2

What forms as a result of the chemical weathering of feldspar? Quartz Sand grains Clay minerals Limestone

What is the weight of a person with a massa of 80kg

True or False Visible light is a kind of electromagnetic wave.

Nikolas, the fire extinguisher, and the skateboard have a combined mass of 50 kg. What force would the fire extinguisher have to produce to propel Nikolas if he wanted to accelerate at a rate of 1.

A set of data is collected from a simple circuit with a 20 resistor and is represented in the table

A skydiver of mass m jumps from a hot air balloon and falls a distance d before reaching a terminal velocity of magnitude v. Assume that the magnitude of the acceleration due to gravity is g. a.

8. What happens to force when mass is increased?

Give an example of ionic and covalent bond, and explain and make an example for each.
