Science key concepts Flashcards
1
Q
A force is required to do what?
A
to change the velocity of an object
2
Q
How an object changes velocity depends on what
A
depends on the direction of the force exerted
3
Q
A stronger force can cause what
A
A greater change in velocity
4
Q
If the same strength force is exerted on two objects but have different masses
A
the object with less mass will have a greater change in velocity
5
Q
When two objects collie, a force is exerted on each object
A
The two forces are exerted in the opposite directions, but they are the strength same
6
Q
Even though the force exerted on each object in a collision is the same strength
A
I-+f objects have different mass their will be different changes in velocity
