Newtons 2nd Law
F=ma
100
What is acceleration?
Acceleration is the rate of change of velocity. It is the amount that velocity changes per unit time.
100
What is distance?
the length of the path an object is taking
100
how do you find speed
100
what is a balanced force
Balanced forces are forces where the effect of one force is cancelled out by another.
200
Newtons 1st Law
An object in motion will stay in motion unless acted upon by an unbalanced force
200
how do you find acceleration?
200
What is displacement
the overall change in postion
200
what is speed?
Speed is defined as a measure of the distance an object travels in a given length of time.

Newtons 3rd Law
Every action has an equal and opposite reaction

A car takes 8.0 s to accelerate from rest to 28 m/s.
what is the final velocity
28m/s

pammy runs 2m south then 3m north
what is the total distance?
5m
300
What is velocity
measure of the distance an object travels in a stated direction in a given length of time.

30N-->
400
how do you find the acceleration
A=F/M

A car takes 8.0 s to accelerate from rest to 28 m/s.
What is the change in velocity?
28m/s

pammy runs 2m south then 3m north
what is the displacement? include the direction
1m North
400
a car travels 100m in 5s
calculate the speed
s=100/5 = 20m/s

Shortly after a ball is dropped, the air resistance is 5 N and the weight of the ball is 8 N.
3N down
500
how do you find mass?
M=F/A

A car takes 8.0 s to accelerate from rest to 28 m/s. Calculate the acceleration of the car.
a=v-u/t
a=28/8
a=3.5m/s2
