Unit 3 Force Total of All

Front

What is a force?

Back

A force is a push or pull acting on an object.

Front

Can an object with net force on it be moving at a constant velocity?

Back

False. An object with a net force acting on it cannot move at a constant velocity.

Front

Which is capable of more force: a man or an elephant pushing on each other?

Back

The elephant is capable of more force.

Front

If Donkey Kong weighs 1000 N and there is an upward force of 800 N, what will happen?

Back

He will move downward and accelerate downward.

Front

How much upward force is needed to make an object weighing 50 N accelerate downward?

Back

Anything less than 50 N.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

What happens when the net force on an object is zero?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass, calculated as weight = mass × gravity.

Front

What is acceleration?

Back

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

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).
