Newtons First Law
This law explains why you keep moving forward when a car suddenly stops.
What is Newton’s First Law of Motion?
The harder you kick a soccer ball, the faster it moves because of this law.
What is Newton’s Second Law?
This law explains why rockets move upward when gases push downward.
What is Newton’s Third Law?
When forces are not equal in size and opposite in direction, they are called this.
What are unbalanced forces?
The distance an object travels divided by the time it takes
An object at rest stays at rest unless acted on by this.
What is an unbalanced force?
If you push a light shopping cart and a heavy one with the same force, this one accelerates more
What is the lighter cart?
When you jump off a small boat, the boat does this.
What is moves backward?
A tug-of-war game where neither side moves is an example of this.
What are balanced forces?
The rate of change in speed and direction of an object.
What is Velocity?
You need to wear a seatbelt in a car because of this
What is Inertia?
If mass increases but force stays the same, acceleration does this.
What is decreases?
For every action, there is one of these.
What is an equal and opposite reaction?
A soccer ball at rest is kicked and starts rolling. This shows what types of force.
What are unbalanced forces?
A car moving at a constant speed but turning is an example of this.
What is changing Velocity? (acceleration)
A soccer ball won’t roll across the field forever because of this force.
What is friction?
A bowling ball takes more force to move than a tennis ball because of this.
What is greater mass (inertia)?
A hammer hits a nail, and the nail does this back to the hammer.
What is pushes back with equal force?
A book resting on a table is an example of this.
What are balanced forces?
If a cheetah runs 300 meters in 10 seconds, its speed is this.
What is 30 m/s?
A book on a desk will not move unless this happens.
What is a force is applied?
This equation shows the relationship between force, mass, and acceleration.
What is F = ma?
When birds flap their wings down, the air does this to help them fly.
What is pushes them upward?
When one force is stronger than another, this happens to the object.
What is the object moves (acceleration)?
A roller coaster moving up and down hills is an example of this type of motion.
What is accelerating?
