Average mass of a toy car (small, hot wheels) ?

Compare the sum of the kinetic and potential energies of the pendulum at position A to the sum at position C. (Ignore friction.)

across a rough, horizontal surface. The chair's mass is 18.8 kg. The force you exert on the chair is 165 N directed 26 degrees below the horizontal. While you slide the chair a distance of 6.00 m, the chair's speed changes from 1.30 m/s to 2.50 m/s.

Two male moose charge at each other with the same speed and meet on a icy patch of tundra. as they collide, their antlers lock together and they slide together with one-third of their original speed. what is the ratio of their inertias?

What do we mean by gravitational time dilation? A) It is the idea that time runs slower in places where gravity is stronger. B) It is the idea that clocks run slow for people moving at high speed past you.

The specific heat of water is 4.19 x 103 J/kg°C. How much energy will it take to raise the temperature of 0.5 kg of water by 2 degrees?

When 2 objects collide and stick together this is referred to as

Fill in the blanks to complete each statement about the heating of Earth's surface. Earth takes in thermal energy from the Sun in a process called Sunlight strikes Earth's surface at different angles. This angle is called the angle of Done Intro

A 2.0-kg block is on a perfectly smooth (frictionless) ramp that makes an angle of 30^/circ30 ∘ with the horizontal. What is the force of the ramp on the block?

What is the difference between negative displacement and negative velocity?
