There was Pat and he wanted to go to the moon. He wanted to check the speed of the rocket to be safe so he won't die. Speed of the rocket was 100m/s. It took him to reach 100m/s in 10s. What was distance he covered in 10s ?
1km
The sum of All forces
Net force
Distance =
Time x Speed
resistance to movement
1st Law of Motion
Km/h
Speed
a roller skater pushes harder with his leg and begins to move faster.
2nd law of motion
How fast an object moves
speed
Force =
Mass x Acceleration
More mass, Less Acceleration
Unit of Net Force
Newtons
Rock skipping on a water.
3rd Law of Motion
Resistance to movement
Inertia
Acceleration =
Vf - Vi / T
An object at rest will stay at rest until an applied force acts on it.
1st Law of Motion
Decades
Time
In speed and time graph, the straight line means ...........................................................................................................................................................................................................................................................................................................................................
Constant speed
Causes objects to slow down
Friction
3rd law of motion =
fa+-fb
when the objects air resistance is more than the applied force
