PLEASE HELP WLL GIVE BRALINEST TO WHOEVERS RIGHT 1. If you are driving down the road, how do you know that the car is moving (think about your reference point)?

2. Why is it important to include units when describing motion?

3. In the international system of units, what units are used to measure distance?

4. Describe how speed is measured (what are the units)

5. A car moving at a constant speed changes direction. Is the car accelerating? How do you know?

6. How do you calculate speed?

7. A family is traveling south to Florida for a 5 day Disney vacation. The are traveling 105 km per hour during the trip. Is this an example of SPEED OR VELOCITY and how do you know.

your answer would be fusion

answer; how far out of place which the object finished relative to the starting location;

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

i think it would be 5
