velocity
Average velocity can be calculated by dividing displacement over?
by time
How could you accelerate by using a car?
Hitting the gas or the brakes
What happens according to newton if you let an untied balloon go?
Air will rush out of the balloon forcing the balloon to move through the air in the opposite direction , but equal force.
newtons third law of motion
A car moved 80 km to the south, what is the displacement?
80km
when an apple is falling from a tree what is it considered?
acceleration
How do newtons law affect your daily life?
Everything that happens in our lives can be connected back to one of newtons 3 law of motion since force is involved in everything
When would an object have a zero velocity even if it is moving?
When it goes in a particular direction
What is the relationship between acceleration and velocity?
Acceleration is the rate of change of its velocity
What will happen if you are riding a skateboard and hit something?
Your body will keep moving forward and fly off your skateboard since the curb only stops the board , not yourself
1st law of motion
how does a pilot use velocity calculations to navigate a plane?
by factoring in the aircraft, airspeed wind speed and direction
How will a skydiver velocity change when a parachute first opens?
The speed will suddenly decrease.
Is throwing a ball up free fall?
Yes because even when an object is thrown upward it has zero velocity. because the action of gravity pulls it back down
In a race , why is it important to consider both speed and velocity?
They help us understand the motion of objects around us , cars includes speed as well as direction of motion.
What is acceleration?
rate at which velocity changes with time in terms of both speed and time
You throw a beanbag in the air and catch it 2.2 s later at the same place at which you threw it
10.78 m/s
