Unit Review --- Forces

Front

What is the formula to calculate force?

Back

Force (F) = Mass (m) × Acceleration (a)

Front

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

Back

Newton (N)

Front

If a 20 kg object accelerates at 10 m/s², what is the force applied?

Back

200 Newtons

Front

What does it mean for forces to be balanced?

Back

Balanced forces result in a net force of 0 N, meaning there is no change in motion.

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account all individual forces.

Front

When a bird flies, what direction does the air push against its wings?

Back

UP

Front

When a swimmer pushes backward against the water, what direction does the water push against their arms?

Back

FORWARD

Front

What is inertia?

Back

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

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

Acceleration is directly proportional to the net force and inversely proportional to the mass.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.
