SLO 2 Forces & Motion Review

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

Define net force.

Back

The vector sum of all the forces acting on an object.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m) or a = F/m.

Front

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

Back

Newton (N).

Front

Explain the concept of friction.

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight (W) = Mass (m) × Gravitational acceleration (g).

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

How do you calculate the normal force acting on an object resting on a horizontal surface?

Back

The normal force (N) is equal to the weight of the object when there are no vertical forces acting on it: N = Weight = m × g.

Front

What is the significance of the slope of a velocity-time graph?

Back

The slope of a velocity-time graph represents the acceleration of the object.

Front

Define inertia.

Back

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