1
Aim: How does the force of gravity affect objects? Do Now: Complete worksheet

2
Gravity is the force of attraction between 2 objects All objects exert gravitational force.

3
Newton’s Law of Universal Gravitation States that the force of gravity depends on 2 factors: the mass of the objects and the distance between them.

4
Objects escape earth’s gravitational pull only if ….. A force greater than gravity is be used to move objects through the gravitational pull of earth and space.

5
The rate at which an objects falls is 9.8m/sec/sec For every second an object drops, its velocity is increasing by 9.8m/sec/sec.

6
What will fall to the ground first… A cannon ball with a mass of 100kg OR a cannon ball with a mass of 50kg?

7
The winner is… BOTH will land at the same time. This is because both objects are speeding at the same rate 9.8m/sec/sec All falling objects accelerate at the same rate However, air resistance will effect the objects.

8
So what about a falling… Marble Rock Boulder Which will land first?

9
The winner is… They will all land at the same time …all fall at the same rate of gravity. Which is… 9.8m/sec/sec

10
A piece of paper does not fall at 9.8 m/s/s because its acceleration is much less Because……. Air resistance

11
SUMMARY Every object exerts ___________ force on every other object. Gravitational force depends on how much___________ the objects have and on how far apart they are. __________ is one of the forces acting on orbiting objects and projectiles. gravitational mass Gravity
