According to Newton’s third law of motion, if someone jumps off a skateboard, the skateboard will roll backward because –

the force that sent the person forward, there is an equal force pushing back on the skateboard.

Why does the Moon have a greater effect on ocean tides than the Sun?

The Moon has a greater gravitational pull on Earth’s oceans because it is much closer.

An amusement park ride uses electricity to make its motor spin. The ride also makes noise and lights up. Which observation of the amusement park ride demonstrates the law of conservation of energy?

The amount of electrical energy used equals the total amount of mechanical, sound, and light energy produced.
