Total questions: 10
Worksheet time: 6mins
What kind of motion is modeled by the graph?
constant speed
no motion
accelerating speed
decreasing speed
What is Newton's second law?
Force = mass x acceleration
If the net force of an object is zero, the motion of the object does not change
When an object applies a force on another object, the second object applies an equal but opposite force on the first object
What is gravity?
A force that one object can apply to another object without touching it
the force that pushes perpendicular to the object's surface
an attractive force between all objects that have mass
the forces two objects apply to each other
What are the 4 main forces that act on an object?
1. Gravity
2. inertia
3. applied
4. normal
1. Friction
2. Weight
3. Normal
4. Gravity
1. Applied
2. Abnormal
3. Friction
4. Gravity
1. Gravity
2. Friction
3. Applied
4. Normal
The rougher the surface, the (a) friction
What is static friction?
Friction of an object that is not moving
When two solid surfaces slide over each other
when an object rolls across a surface
when a solid object moves through a fluid
What is an example of fluid friction?
sky diving
ice skating
standing still
running
What is an elastic collision?
When objects collide and stick together
When two objects collide and bounce off each other
the force that two objects apply to each other
Balanced forces won't cause a change in (a) .
When the only force acting on objects is gravity, all objects...
fall with the same acceleration
Have no weight
fall at 9.8 s2m
fall at different speeds
