Force & Motion Vocab

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law of Motion states that if one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction of the first object.

Front

What force pulls objects toward each other?

Back

Gravity is the force that pulls objects toward each other.

Front

What is the distance an object travels per unit of time called?

Back

Speed is the distance an object travels per unit of time.

Front

What does Newton's 2nd Law of Motion state?

Back

Newton's 2nd Law of Motion states that acceleration depends on the object's mass and the net force acting on the object.

Front

What is the overall force on an object when all individual forces are added together?

Back

Net force is the overall force on an object when all individual forces acting on it are added together.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula: Force = Mass x Acceleration.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.
