Force and Motion

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

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

Back

Subtract the smaller force from the larger force. The direction of the net force is in the direction of the larger force.

Front

What is the net force when a 45 N force and a 32 N force act in opposite directions?

Back

13 N in the direction of the 45 N force.

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies toward each other, commonly experienced as the force that pulls objects toward the Earth.

Front

What is inertia?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to a change in speed or direction.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, representing the quantity of motion an object has.
