Back

An unbalanced force is when the resultant force acting on a body is not equal to zero, causing the body to move or change its direction, size, or shape.

Front

What is a variable in science?

Back

A variable is a letter or symbol that represents a number that can change.

Front

What is acceleration?

Back

Acceleration is the rate at which velocity changes.

Front

What is net force?

Back

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

Front

What is a reference point?

Back

A reference point is a place or object used for comparison to determine if an object is in motion.

Front

What is a balanced force?

Back

A balanced force occurs when the forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is inertia?

Back

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

Front

What is speed?

Back

Speed is the distance traveled by an object in a given amount of time.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.
