Calculating Net Force

What is net force?

• Net force is the total force acting on an object when all the individual forces are combined.

• Net force is the force that opposes motion.

• Net force is the force that acts only on stationary objects.

• Net force is the sum of all forces acting on an object in one direction.

What is the difference between mass and weight?

• Mass is the amount of matter in an object, measured in kilograms (kg), while weight is the force of gravity acting on that mass, measured in Newtons (N).

• Mass is the force of gravity acting on an object, while weight is the amount of matter in an object.

• Mass and weight are the same and can be used interchangeably in physics.

• Mass is measured in Newtons (N), while weight is measured in kilograms (kg).

What is a free-body diagram?

• A visual representation of all the forces acting on an object, used to analyze the net force and motion.

• A diagram that shows the internal structure of an object.

• A chart that lists all the possible outcomes of an experiment.

• A graphical representation of the energy transformations in a system.

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

• Add the magnitudes of the forces together.

• Subtract the smaller force from the larger force.

• Multiply the forces together.

• Divide the total force by the number of forces.

What is an example of unbalanced forces?

• A car parked on a hill

• A soccer ball being kicked

• A book resting on a table

• A person standing still

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

• The object will accelerate in the direction of the net force.

• The object will remain at rest or continue to move at a constant velocity.

• The object will eventually come to a stop.

• The object will change its direction of motion.

What is acceleration?

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

• Acceleration is the force applied to an object.

• Acceleration is the speed of an object in a straight line.

• Acceleration is the distance traveled by an object over time.

How does gravity affect net force?

• Gravity pulls objects toward the center of the Earth, contributing to the overall force acting on the object.

• Gravity has no effect on net force as it only acts on objects in free fall.

• Gravity increases the net force by pushing objects away from the Earth.

• Gravity only affects the net force of objects that are stationary.

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

• Add the two forces together

• Subtract the smaller force from the larger force

• Multiply the two forces

• Divide the larger force by the smaller force

What is friction?

• A force that accelerates an object in motion.

• A force that opposes the motion of an object. It acts in the opposite direction to the movement.

• A type of energy that increases with speed.

• A force that has no effect on moving objects.
