Force
This is defined as a push or a pull on an object.
What is a force?
This law states that an object at rest stays at rest and an object in motion stays in motion unless acted on by a force.
What is Newton’s First Law?
This law describes the relationship between force, mass, and acceleration.
What is Newton’s Second Law?
This law states that for every action, there is an equal and opposite reaction
What is Newton’s Third Law?
This force opposes motion when two surfaces rub together.
What is friction?
These are two ways forces can affect motion: they can make an object start moving or do this opposite action.
What is stop moving?
If an object has more mass, it has more of this and is harder to move or stop.
What is inertia?
This formula shows how force, mass, and acceleration are related.
What is F = ma?
When you jump, you push down on the ground, and the ground does this to you.
What is pushes you up?
This force pulls objects toward each other and keeps us on the ground.
What is gravity?
This term describes the total of all forces acting on an object.
What is net force?
According to Newton’s First Law, motion only changes when this acts on an object.
What is a force?
When force increases, this also increases (if mass stays the same).
What is acceleration?
When walking, you push backward on the ground, causing you to do this.
What is move forward?
This is the amount of matter in an object and does not change based on location.
What is mass?
When the net force equals zero, forces are described using this term
What are balanced forces?
This term describes an object’s tendency to resist changes in its motion.
What is inertia?
If mass increases while force stays the same, this decreases
What is acceleration?
This describes the relationship between action and reaction forces.
What is equal in size and opposite in direction?
This is the force of gravity on an object and can change depending on where you are.
What is weight?
These forces cause an object’s motion to change because the net force is not zero.
What are unbalanced forces?
This is what happens to an object in motion if no forces act on it.
What is it continues moving in the same direction at the same speed?
This explains why a heavy object needs more force to move than a light object.
What is it has more mass, so it resists acceleration more?
When air rushes out of a balloon, the balloon moves in this direction relative to the air.
What is the opposite direction?
This explains why brakes can stop a bike and shoes can grip the floor.
What is friction slowing objects down?
