5 days ago · 1 kilometre per hour = 1,000(meters) / 3,600(seconds) Which means, 1 km/hr= 5/ 18 m/s . This article explained what is a kilometre, how to convert a metre into kilometre, centimetre, millimetre into a kilometre in detail.
Jan 25, 2023 · 1. Distance is in metre ( m) and time in seconds ( s), then the speed is in metre per second ( m s – 1 or m / s ). 2. Distance is in kilometre ( k m) and time in hours ( h) then the speed is in kilometre per hour ( k m h – 1 or k m / h) To find the distance, if: Speed is in ( m s – 1), time must be in second.
The Astronomical Unit (AU) is the mean distance from the Earth to the Sun, 1.496 × 10 13 cm, or about 93 million miles. A light-year (ly), the distance travelled by light in one year, or 9.46 × 10 17 cm. More significantly, one light-year is equal to 9,500,000,000,000 kilometres. The parsec (pc), the distance at which an object has a ...
changing directions real changing speed. What's the formula for acceleration? To be specific, acceleration is defined to be the rate of change of the velocity. a = Δ v Δ t = v f − v i Δ t.
- an alternative way of thinking about it would be if velocity equals rate x direction, if you change any variable in that it would change the veloci...
- Quite late, but "flooring it" does refer to suddenly speeding up, and applies especially to cars- It stems from the fact that (at least in older ca...
- Good, clear question. Maybe this helps... F=ma right? so if they are equal, they are in the same direction. Kinda makes sense I guess: if you push...
- Probably no. And the force that drag us backward IS inertia. (Sorry if I'm mistaken. You seemed to treat inertia and 'the force that drag us backwa...
- It all depends on what directions you assign to positive direction of your axis, if it is in the positive direction then is it positive.
- Speed is the magnitude of velocity. Velocity is a vector, which means it has two parts: first, your velocity has a magnitude, which just answers th...
- Your current velocity is 34 m/s in the opposite direction of what is considered the "positive" direction, so it is -34 m/s. Acceleration, 8 m/s^2,...
- Generally, the right side is indicated as the positive direction whilst the left side as the negative direction.
- Just look at the direction of the CHANGE in velocity. If the change is toward the positive direction, it's positive.

Feb 20, 2024 · In physics, displacement refers to an object's change in position. For example, if you walk 1 mile (1.6 kilometers) down the street to your friend's house, your displacement is 1 mile (1.6 kilometers). But if you hike a 1-mile (1.6-kilometer) loop that starts and ends at the same point, your displacement is actually 0.
