Unit 2 Final Review

Front

What is the force that opposes the motion of an object sliding across a surface?

Back

Force of friction.

Front

If a constant force is applied to two objects of different masses, which object will have a greater acceleration?

Back

The object with the smaller mass will have greater acceleration.

Front

What is the definition of net force?

Back

The overall force acting on an object, taking into account all individual forces.

Front

What is the force that acts perpendicular to the surface an object is resting on?

Back

Normal force.

Front

Which type of forces cause an object to accelerate?

Back

Unbalanced forces.

Front

What is the formula for calculating acceleration?

Back

Acceleration = Net Force / Mass.

Front

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

Back

The object will not accelerate; it will remain at rest or continue moving at a constant velocity.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases.

Front

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

Back

Newton (N).

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not cause a change in motion.
