class 9 chapter force and law of motion
Answers
Given :-
Mass = 2000 kg
Force = 1000 N
To Find :-
Acceleration
Solution :-
We know that
F = ma
Where
F = force
m = mass
a = acceleration
By putting values we get
1000 = 2000(a)
1000/2000 = a
1/2 = a
0.5 = a
Therefore
Acceleration is 0.5 m/s²
Provided that:
- Force = 1000 Newton
- Mass = 2000 kg
To calculate:
- The acceleration
Solution:
- The acceleration = 0.5 m/s sq.
Using concept:
- Force formula
Using formula:
Where, a denotes acceleration, F denotes force and m denotes mass
Required solution:
Additional information:
Explanation to calculate net force: If forces are acting on the same direction then add them and if they are acting in opposite directions then subtact them.
★ Condition first if forces are acting in the same direction, then the net force!?
- Kindly refer to attachment 1st
→ Net force = Force A + Force B
→ Net force = 20 N + 20 N
→ Net force = 40 Newton
Condition second if forces are acting in the different or opposite direction, then the net force!?
Kindly refer to attachment 2nd
→ Net force = Force A - Force B
→ Net force = 20 N - 20 N
→ Net force = 0 Newton
