First law
According to Newton’s First Law, an object at rest will stay at rest unless this acts on it.
What is an unbalanced force
If you push a light box and a heavy box, which one accelerates more?
The unit of force
What is a newton
A tiny car accelerates more than a big truck when both are pushed with the same force cause the car has less of this
What is mass
speed measures how fast something is moving while this also includes direction
what is velocity
A soccer ball will not move until you kick it. This is an example of this law.
What is Newton’s First Law of Motion
if a 5kg object accelerates at 2 ms what is the force
10 Newtons
The unit of mass
Kg
When a car stops suddenly passengers move forward because of this
what is newtons second law/inertia
a car travels 100 km in 2Hr/This is its average speed
what is 50 km
When a car suddenly stops, your body keeps moving forward. This is because of this property.
What is inertia
If you double the force on an object what happens
It doubles
The unit of acceleration
what is meters per second
when you throw a tennis ball and a bowling ball with the same force this one goes farther
What is the tennis ball
This is the reason why you need to wear a seat belt in a moving car.
What is Newtons first law
Newtons second law of motion
A 12 kg box is pushed with a force of 24 N According to Newton’s Second Law, the box’s acceleration is this
what is 2 m/s2
This safety feature in cars increases the time of impact reducing force on passenger
what is a airbag
these are the three things Newton’s Second Law
what are force and mass and acceleration
when you ride your bike up a hill the main opposing t force is this
What is gravity
A 20 kg cart is pushed with a net force of 40 N. according to newtons second law its acceleration is this
What is 2 m/s2
a 2kg ball is pushed with a 4N force its acceleration is this
2 m/s
