Unit 2 Final Review

Front

What is net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction of motion.

Front

Which object will have the greatest acceleration when struck with the same amount of force?

Back

The object with the least mass will have the greatest acceleration, according to Newton's second law (F=ma).

Front

What is the applied force?

Back

The applied force is the force exerted on an object by a person or another object, causing it to move or change its motion.

Front

What causes acceleration?

Back

Unbalanced forces cause acceleration. When the total force acting on an object is not zero, the object will accelerate in the direction of the net force.

Front

What forces act on a leopard laying on a log?

Back

The forces acting on the leopard are the force of gravity (F_g) pulling it down and the normal force (F_N) exerted by the log pushing it up.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) can be calculated using the formula a = F/m, where F is the net force and m is the mass of the object.

Front

What is the difference between balanced and unbalanced forces?

Back

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

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surface of contact.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the Earth and an object, pulling the object towards the center of the Earth.

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with a stable surface, acting perpendicular to the surface.
