A push or a pull
Force
What is a change in speed in a certain amount of time?
Acceleration
How is speed calculated? (What is the equation for speed?)
speed = distance / time
Which direction will the rope move?
To the left
What is the difference between mass and weight?
Mass is how much matter/stuff is in something, weight is how much gravity pulls down on something
What force keeps us on the ground?
Gravity
What type of friction is used when the brakes of a car is stepped on?
Sliding friciton
Car #1
Ms Sinclair pushes against a large box with a force of 15N. The box doesn't move. What is the amount of force exerted on the box by Ms Sinclair?
15N
What is the force that opposes the motion of touching surfaces?
Friction
What tool is used to measure force?
Spring scale
How did releasing the cart from a lower place on the ramp affect how far it moved the block?
The block did not move as far (less acceleration)
What is the speed for the first 30 minutes of the trip?
0.13 km/min
If Ms Sinclair pushes on a box with a force of 20N and Ms Baranja pushes on the same box with a force of 15N, what is the net force pushing the box?
35N
What kind of friction is shown in the picture?
Sliding friction
How did increasing the mass of a cart affect how it hit a wooden block?
The cart hit the block with more force.
Which graph shows acceleration?
Graph B
The speed at a specific moment
Instantaneous speed
If Ms Sinclair pushes on a box with a force of 20N and Ms Baranja pushes on the other side of the box with a force of 15N what is the net force on the box?
5N
What kind of friction is shown in the picture?
Rolling friction
What will happen to the force exerted on the pins if a heavier bowling ball was used?
The force on the pins will increase
What will happen to the force exerted on the pins if the ball is rolled faster?
The force on the pins will increase
Speed that does not get faster or slower.
If Ms Sinclair pushes on a box with a force of 20N and Ms Baranja pushes on the other side of the box with a force of 20N describe what will happen to the box.
Nothing, the box will not move.
What type of friction is shown in the picture?
Fluid Friction
