New cards
What will happen to the trees if the truck stops abruptly at 55 mph?
The trees will likely continue moving forward due to inertia and could fall off the truck.
2
New cards
What is the formula for speed?
Speed = Distance/Time
3
New cards
What is the formula for velocity?
Velocity = Displacement/Time
4
New cards
What must also be stated when determining velocity?
The direction of the displacement must be stated.
5
New cards
State the definition of velocity.
Velocity is the speed of an object in a particular direction.
6
New cards
Is a dog chasing a cat an example of balanced or unbalanced forces?
Unbalanced forces.
7
New cards
Is a child sitting on a swing an example of balanced or unbalanced forces?
Balanced forces.
8
New cards
Is a stalk of corn growing upward an example of balanced or unbalanced forces?
Unbalanced forces.
9
New cards
Is an airplane flying from DFW to Philly an example of balanced or unbalanced forces?
Unbalanced forces.
10
New cards
Is a cow lying in the grass an example of balanced or unbalanced forces?
Balanced forces.
11
New cards
Is a burger cooking on the grill an example of balanced or unbalanced forces?
Balanced forces.
12
New cards
What type of force is exhibited when an object moves from its resting position or stops moving?
Unbalanced force.
13
New cards
What units is speed in?
Speed is typically measured in meters per second (m/s).
14
New cards
When calculating an object’s net force, what else must you state besides the force produced?
The direction of the force must also be stated.
15
New cards
What was the student's speed in m/s if she ran 600 meters in 844 seconds?
Speed = 600m/844s = approximately 0.709 m/s.
16
New cards
What was Paige's speed if she swam the 200 meter race in 10 seconds?
Speed = 200m/10s = 20 m/s.
17
New cards
Are the forces of gravity and air friction balanced?
No, they are generally unbalanced during free fall.
18
New cards
What would happen to a falling object because of gravity and air friction?
The falling object would accelerate until the forces balance, reaching terminal velocity.
19
New cards
What is NET FORCE?
Net force is the total force acting on an object, taking into account both magnitude and direction.
20
New cards
What is the net force on the object shown with 5N
The net force is 2N to the right (7N - 5N = 2N).
