Newtons second law says that the acceleration of an object (produced by a net force) is directly proportional to that magnitude of the net force. E.g. F = ma
where F is the net force of an object, m is mass and a is acceleration.
For example, if an object had a large mass, there would have to be more force in order to move it than if it was lighter.
In a linear motion, if you pushed two objects, one slightly larger than the other, with the same force, the acceleration of the smaller object would be bigger than the larger one. So the motion (change in position over time), of the larger object would be seen as lesser than the smaller one (in a situation where both forces are equal).
Answer:
8 and 093 over 0.6 then 303
Explanation:
cross over the numbers and get the answer
Speed is represented by distance divided by time. Graphically, constant speed is represented by a horizontal line on a speed-time graph.
<u>Explanation</u>
- In a very literal sense speed is considered to be scalar quantity and denotes how fast or quick objects move. Therefore, speed is considered to be the velocity or swiftness of an object to cover a certain amount of distance.
- There three types of speed high speed, average speed, and zero speed. Any object which moves at very high speed or moves very fast and quickly and subsequently can cover the considerable distance is called high-speed object. On the other hand, the average speed of an object is defined as the total distance covered divided by the time taken to cover that distance. Again when the object doesn't cover any distance at a given time or any object which has got no movement in it is called zero speed object.
- Constant speed objects are those objects which move at a constant speed. Constant speed here refers to mean objects which move at the same speed without increasing or decreasing.If we try to represent constant speed on the diagram or through graph it can be done by drawing a horizontal line on the speed-time- graph. Here Mr. Robert drives his car at a constant speed means that he was driving his car without increasing or decreasing the speed or at the same speed.It has the same increase in distance in the given time. Time increases at the right and distance increase constantly with time.
Answer:
a. 3.6 units
b. 1.4 units
c. 3.6 units
d. 6.1 units
Explanation:
The length of a vector is given by the following formula:
Length = √(x² + y²)
where,
x = x-component of vector
y = y-component of vector
a.
Here,
x = 2
y = 3
Therefore,
Length = √(2² + 3²)
Length = √13
<u>Length = 3.6 units</u>
<u />
b.
Here,
x = 1
y = 1
Therefore,
Length = √(1² + 1²)
Length = √2
<u>Length = 1.4 units</u>
<u />
c.
Here,
x = 2
y = -3
Therefore,
Length = √(2² + (-3)²)
Length = √13
<u>Length = 3.6 units</u>
<u />
d.
Here,
x = 1
y = -6
Therefore,
Length = √(1² + (-6)²)
Length = √37
<u>Length = 6.1 units</u>
