speed
what is speed (this is too easy)
a measure of how fast something moves
what is precision shown by?
the number of significant figures
what is a distance time graph
a way of showing how something is moving
what is acceleration
when the amount of speed increasing in a second (or somthing like that)
if the resultant force is 0, are the forces balanced or unbalanced
balanced
formula for speed
speed = distance/time
what is reaction time?
the delay, the time it takes for the brain to process information
the steeper the slope or gradient is ,the faster the speed. true or false?
true!
what is the formula of acceleration?
acceleration=change in speed/time
when you stands on the ground why don't you float or get pushed into the ground?
because all the forces acting on you are balanced
what is instantaneous speed and give and example irk of like you know what i mean
speed at a moment in time, a speedometer on a car(accept other correct examples)
describe how a target with high precision and low accuracy would look like or if possible draw and send to WhatsApp
the darts would be all together in one place but not close to the bullseye(middle)
a horizontal line means the object is _______
stationary (not moving)
if something is decelerating or getting slower the the acceleration is ______
if something is decelerating or getting slower the the acceleration is negative (its in the book check if u dun believe me
what is a resultant force?
the single force equivalent to 2 or more forces acting on an object(accept an example)
what is and how do you calculate the average speed
the total distance travelled divided by the total time taken for a complete journey
what tool can you use to be more accurate in time measurements
light gates or timing gates
a more realistic distance time graph would have_____
curved lines
what is the acceleration in this graph(ill send on whatsapp)
10m/s2
If something is moving then there must be a resultant force. true or false
false! (if anyone wants to explain, no points but just explain)
Lily is going to school from home. She stops at a candy shop which takes her 2 minutes to get to and is 4 meters from her house. She gets to school 3 minutes later and walks 6 meters from the candy shop. What is her average speed in meters per second?
1.2m/s
how many seconds is the reaction time usually
0.2 (was this too easy)
calculate the speed shown in this graph(im goiong to send one on whatsapp
1m/s
a ball decelerates from 10m/s to 0 m/s in 0.1 secs
calculate the acceleration and deceleration of the ball
acceleration=-100m/s2
deceleration=100m/s2
Describe the difference between balanced and unbalanced forces. Provide an example scenario where both types of forces are acting on an object and explain how each scenario affects the motion of the object.
Balanced forces are equal in magnitude but opposite in direction, resulting in no change in motion (e.g., a stationary box). Unbalanced forces are unequal, causing acceleration in the direction of the greater force (e.g., a box moving when one side pushes harder). accept similar answer
