Inertia
Balloon cars are an example of Newton's ____ law of Motion? Explain
3rd
for every action equal and opposite reaction
air comes out of balloon which pushed the car forward
a. An object's acceleration is dependent upon shape and gravity.
b. An object's acceleration is dependent upon mass and net force.
c. An object's acceleration is dependent upon friction and weight.
d. An object's acceleration is dependent upon air resistance and velocity.
An object's acceleration is dependent upon mass and net force.
Speed = 360 km/ 4 h=
90 km/h
25 N to the right and 20 N to the right =
45 N to the right
Force=Mass * Acceleration
A player catches a ball. The action force is the impact of the bat against the ball. The reaction force is:
The force the glove exerts on the ball.
If a 1600 kg car is accelerating at a constant rate of 4 m/s2 and suddenly hits a wall, what would be the force of the crash?
F=M*A
6400 N
What is the equation for Acceleration?
Final Velocity - Initial Velocity/ Time
10 N to the left and 12 N to the right =
2 N to the right
What is the force necessary to accelerate a 50 kg object at a rate of 3.2 m/s2?
160 N
F= 50kg* 3.2 m.s2
Newton’s third law states that all forces occur in equal but oppositely directed pairs. (For every action, there is an equal and opposite reaction). Use Newton’s 3rd Law to answer the question below: A baseball player bats a ball with a force of 1,000 N. The ball exerts a reaction force against the bat of:
1,000 N
45N
