Net Forces

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration and direction of motion.

Front

How do you calculate net force when multiple forces are acting in the same direction?

Back

To calculate net force when multiple forces are acting in the same direction, you add the magnitudes of the forces together.

Front

How do you calculate net force when multiple forces are acting in opposite directions?

Back

To calculate net force when forces are acting in opposite directions, you subtract the smaller force from the larger force and take the direction of the larger force.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the SI system is the Newton (N).

Front

What does it mean for forces to be balanced?

Back

Forces are balanced when the net force acting on an object is zero, resulting in no change in the object's motion.

Front

What does it mean for forces to be unbalanced?

Back

Forces are unbalanced when the net force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

Front

If a toy car is moving at a constant speed, what can be said about the forces acting on it?

Back

If a toy car is moving at a constant speed, the forces acting on it are balanced.

Front

What is the effect of a net force of 1.3 N to the right on an object?

Back

A net force of 1.3 N to the right will cause the object to accelerate to the right.

Front

What happens to an object's speed if the net force acting on it is zero?

Back

If the net force acting on an object is zero, the object's speed remains constant.

Front

In a scenario where a group of students pulls carts with the same force, what determines which cart has the least change in speed?

Back

The cart with the greatest mass will have the least change in speed when pulled with the same force.
